Cracklock Manager
Cracklock can be used for other purposes as well, for instance developers have used it to certify their software for 'Year 2000' compliance. Since then we've improved Cracklock and are now proud to announce that it can also certify your software against the Y10K bug (aka 'bug of the year 10000').
Amongst the different computer viruses that are roaming the Internet, there are the so-called 30th-day viruses which usually appear exactly thirty days after the installation of the infected software. Cracklock is a tool that allows us to avoid the execution of any of these programs.
Stop the time for specific programs
What this software basically does is freeze the runtime of a program. In other words, users can add any of the programs installed on our computer to stop the time specifically for each one of them. That means that we can keep a fixed date and time so that that time never goes by and the virus that is scheduled to start running on a certain day, never does so.
- Cracklock Change Log 3.9.44 - 16 March 2008. Fixed: The setup does not set write permissions for the Cracklock.settings file, so if the user chooses to store settings in cracklock's directory then it is impossible to add applications to Cracklock.

- Cracklock is the leader in the hard task of repairing a bug present in a growing number of sharewares and exploited by a polymorph virus known as the '30th day' virus. As its name implies, the virus manifests itself only once you have run the infected software for a certain period of.
Nevertheless, this program can be used for other purposes, such as testing any problem that may result from the arrival of a certain date (remember the so-called Year 2000 problem) or even stop the time in trial versions of programs that expire. In any case, we have to point out that it doesn't work with all programs.
Introduction
Freeware, No Adware, No Spyware.
The current version support all 32 bits versions of Windows from NT to Vista (NT/2K/XP/Vista). For legacy version of Windows (95, 98 or ME), please download version 3.8.3 from my website.
For the latest version, check the website at https://william.famille-blum.org.
You probably know the most polymorphic and sadistic virus of this ending century, the so-called '30th day virus'. It attacks the best sharewares as well as the worst ones, introducing as soon as you install them a bug that prevents them from running beyond a random delay, often 30 days. Cracklock has the leadership in the fighting challenge against this virus that even McAfee, Norton, Sophos, Thunderbyte and F-Proot seem unable to deal with.
Cracklock is also a tool that developpers may use to check Y2K-like compatibility for their products without having to change the system time, thus avoiding side-effects.
What's new ?
It is now possible to run Cracklock from a usb flashdisk. In this mode, the settings are saved on disk in a Cracklock.settings file. By default this file is stored along with cracklock binaries. An option let you tell cracklock to save the settings in the current user's Appdata folder or in the Windows registry.
Another option can be set to store the per-application settings in each application's directory. If you run an executable file called 'App.exe' that is (statically or run-time) injected by Cracklock and if there exists an associated configuration file called 'App.exe.cracklock' next to it in the application directory then Cracklock will load the settings from that file instead of the general cracklock setting storage (the registry or the main setting file).
Features
A new installation program: simplifies the install process of Cracklock.
The Manager: an interface which allows you to set up each Cracklock-controlled software an easier and faster way.
Multilingual: Cracklock has been translated to many languages.
Contextual help: you can obtain help from anywhere, at any time !
Installation
Just run the setup executable file and follow the instructions on the screen.
**Note to users of older versions of Cracklock:** If a previous version of Cracklock is installed on your computer, it is better to uninstall it before installing the new version.Uninstallation
Choose 'Cracklock' from the list of applications in the Add/Remove programs applet of the Windows control panel.
Usage
How does it work?
Cracklock controls a list of programs you set up. When a program from this list needs time or date, Cracklock operates, bluffing the calling program and returning the pre-determined date or time you have set. So, the program 'thinks' to be at the date/time it accepts for running.
For the end user Cracklock protects you from the 30th day bug, a defect that is becoming very frequent in nowadays software. A program affected by this bug will fail to run when a certain period of time has passed after its installation. For the developer: a safe method for Y2K testing With the help of Cracklock, developers can readily test or check the 'Year 2000 compatibility' (Y2K) of their software.Suppose that you want to check the program you are developing for Y2K compatibility. To perform the test you decide to change the global system date/time to 31th december 1999 and then launch your program in order to debug it. The drawback of this method is that it affects all the programs currently running on the machine. One consequence is that the date stamp of the files created or modified by any software running on Windows will be set to 31th december 1999.
Some other software may even stop working, as if they were 'lost in time'. That would be the case for all these poorly developed softwares that are affected by the notorious '30th day bug'. If you run such software while you are testing your program against Y2K compliance, then you will run into trouble: the bugged sofware will be confused about the date and will stop working.
Cracklock overcomes all these problems by allowing you to specify the date on an application basis.
Setting up an application for Cracklock
Start the manager (shortcut Cracklock Manager in start menu):
**Figure 1. The manager**The Manager lets you add and configure application to be controlled by Cracklock. It lets you do the following 3 basic functions: adding a new application, configure the date and time parameters for an application, and execute the program (though it is not required to launch your applications from the manager).
Adding applications
To add an application to the list of applications controled by Cracklock, click twice on the Add program and then select the executable file of your application. A dialog box will show up to let you configure the parameters for this application.
Note : The application must be a valid 32bits Windows application compatible with Windows 95/98/NT/XP.
Configurating a program for use with Cracklock
Select the program that you want to configure in the manager list. Click on the 'Program' menu then on 'Settings..':
**Figure 2. Program menu**This brings you the configuration dialog box:
**Figure 3. Configuration window**Choose a date and time using the calendar and clock controls.
Click on 'Load preset date/time' in order to load a predefine date/time among the following: the current system date and time, the file creation date/time, the file's last modification date/time.
You can restrict Cracklock to only affect the time, the date or both by selection the approriate raddio button. For instance if you choose to alter the time only then the program will run with the system date but with a fake time. If you choose 'date and time' then both will be faked by Cracklock.
Configuring your applications from the Explorer
You can configure application for Cracklock directly from the Windows Explorer without having to use the Manager. In Windows Explorer, open the directory containing the executable file of your program.
**Figure 4. Windows Explorer**Right-click on the executable file. A contextual menu appears:
**Figure 5. Context menu in Windows Explorer**In this menu, select 'Properties'. A window with several tabs show up, select the tab named Cracklock:
**Figure 6. Cracklock configuration window**If you want to enable Cracklock for this program, check the box Cure this program with Cracklock. Check Show advanced options to show the tabs from the configuration dialog box from the manager.
Advanced options
You may need to tweak some parameters in some cases to make your application work with Cracklock.
System-wide This will affect the system date and time. With this option, each time you run the controlled program, the system computer time and date will be changed to the date/time that you have specified. When the program ends, date and time will be restored to the actual date and time, taking account of elapsed time during usage of the program.The drawback of this method is that all programs running simultaneously are affected together, Cracklock in its native method being precisely designed to affect specific date and time to each program running at one given moment and to avoid this inconvenience.
This option reproduces what you can do yourself manually without Cracklock, with the 'date' or 'time' commands under MS/DOS or with the configuration panel under Windows. In my mind, it has no real benefit.
Freeze date and time This 'freeze' option allows to set a date/time which never changes, as if the time was frozen. Useful for programs that work only during a few hours or minutes.For example, if you set 10:00:00 09/22/1981 for this program, during all the run it will 'think' the time is 10:00:00 09/22/1981.Ten minutes later, the time will still be 10:00:00 09/22/1981 for the application. If the option is not selected, however, at the start the program will have a time of 10:00:00 09/22/1981, and ten minutes later it will be 10:10:00 09/22/1981.
Injection mode In the 'injection mode' tab of the configuration window, you can select between two different modes: static or run-timeWith static-injection, Cracklock will alter the executable file of your application in order to make it load Cracklock. You can additionally tell Cracklock which file it should modify by selecting an executable file among the list of dependencies of your application.The license that you signed when you install a software often prevents you from modifying its executable files - even for the purpose of correcting a bug, as in the present case - so if you have signed such a license then you must not use static injection.
The other mode is 'run-time injection':
Using the run-time injection, Cracklock does not modify any executable file from your application, everything happens at run-time. Note that in this case you need to make sure that the system-wide injection is activated otherwise you will have to start the program from a special shortcut or from wihtin the manager. Imesh.
Starting an application
To execute a program under the control of Cracklock, you can either run it as usual from the shortcut in the 'Start' menu, or selecting the program in the manager and clicking on the Execute menu.
**Special case:** If the run-time injection mode is selected for the application and if system-wide injection is deactivated then then you cannot run the program in the normal way. In this case, you can start your application using one of the following methods:Launch your application from Cracklock manager,
Open up the 'injection mode' tab in the configuration window in the Cracklock manager and click on the link to create a desktop shortcut. You can then run the application directly from this shortcut.
Start the following command:
where 'C:PROGRAM FILESCracklockMCL.EXE' is the full path to the MCL.EXE file installed in the Cracklock directory, C:APPAPP.EXE is the full path to the executable .EXE file of your program, and [program_parameters] are the optional parameters required by your program.
From the Windows Explorer, go to the folder containing your application executable file:
Right-click on the executable file to bring up the context menu:
and select the 'Start with Cracklock' option.
Examples
Cracklock comes with two example applications showing the system date/time. To check that Cracklock works correctly, you can try to configure these two examples in the Manager. These two aplications are located in the 'Examples' subfolder of the Cracklock directory.
**Table 1. Examples**File | Description | Programming language |
|---|---|---|
vcdate.exe | DigClock program from the book Programming Windows 95 by Charles Petzold (Microsoft Press) | Visual C++ |
vbdate.exe | A test program of my own. | Visual Basic 5.0 |
Known limitations
Under Windows NT, Cracklock cannot modify system files like MSVCRT.DLL that are located in the system directory,
the current version of Cracklock doesn't recognize programs configurated with the 1.x and 2.x versions,
Cracklock does not work with 16 bits programs (those designed for Windows 3.1).

Change logs
3.9.44 - 16 March 2008- Fixed: The setup does not set write permissions for the Cracklock.settings file, so if the user chooses to store settings in cracklock's directory then it is impossible to add applications to Cracklock.
- Setup: If some files that need to be updated are in use then it shows a dialog box listing all the applications that need to be stopped before proceeding with the installation/uninstallation.
Important bug fixed: Cracklock did not work in parts of the world where no daylight saving scheme is implemented! (These include the following countries: Afghanistan, Bahrain, China, Hong Kong, Japan, Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, Uzbekistan, Macau, Mongolia, North Korea, Qatar, Kuwait, Saudi Arabia, South Korea, Nepal, Bhutan, Pakistan, India, Bangladesh, Myanmar, Taiwan, Thailand, Laos, Vietnam, Philippines, Cambodia, Malaysia, Brunei, Singapore, Indonesia, Timor Leste, Papua New Guinea, Venezuela)
Chinese translation updated. This may become more useful now that Cracklock works in China ;-)
Fixed: the default parameters for the control panel date and time applet was incorrectly set during installation.
Fixed: small bugs fixed in the Manager.
Manager: Hitting the F5 key refreshes the list
Examples: new clock example written in C#. The VCDate and VBDate have been renamed into C Clock Example and VB Clock Example

New: Support for flashdisk instllation
New: Improvements of the user interface.
New: a manifest file has been added to ensure that version 6.0 of the Windows Common controls DLL is used in order to avoid the annoying beep happening on item selection under Windows Vista.
New: The manager now allows you to configure a command line argument for each application. It will be appended to the command line when the application is runned from within the manager.
New: per-application setting called 'stand-alone mode'. In the normal mode the behaviour is the same as before. In full stand-alone mode, the settings and the injected DLL are copied to the program folder. In a third 'in-between' mode, only the settings are stored in the application folder. When adding a new application, if the file App.exe.cracklock is present in the directory then default settings are loaded from this file. It is deleted when when the application is removed from cracklock.
New: option to let the user change the command parameters that are used to start the application from the Manager.
New: option in the general settings: Shared/Stand-alone installation. In shared mode, Cracklock's directory is added to the PATH environment variable. In stand-alone mode, the injected DLL is copied to each application's folder.
New: The manager now contains a manifest to ensure that version 6.0 of the Windows Common controls DLL is used in order to avoid the annoying beep happening on item selection under Windows Vista.
New: an option in the general settings allows to set the default injection mode when adding new applications to Cracklock.
New: an option that allows one to set the location of the general settings (Registry or INI file). It is also possible to save the application settings in each application's directory (this setting can be overwritten on a per-application basis).
New: a description can be assigned for each application listed in the manager.
New: The documentation is now generated from an XML DocBook file.
Bug fixed: remove a spurious message reporting that CLKERN.DLL is in use when trying to delete it from an application folder.
Bug fixed: In some very particular cases, some API calls were properly hooked.
Bug fixed: The loader now accepts relative paths.
Setup: There is now a new 'Flashdisk installation' mode. In this mode, nothing is written in the Windows Registry and shortcuts are not created.
Setup: a new option let you choose where you want to store the setting file (registry, application data folder or cracklock's folder).
Setup: import the settings from the registry to the INI file if the user choose to store settings in an INI file.
Change: Definition file CLKERN.def regenerated with the latest version of Kernel32.dll
Change: Date mode selected by default when adding a new app.
Change: Icons in the Manager are now shown in 32bits colors.
Fixed: When the import table of a PE file contained more than one occurrences of the module KERNEL32.DLL, the PE file could not be backed-up automatically by the manager.
Bug fix: In some circumstance, the Cracklock manager window positioned itself in the invisible part of the screen.
Fixed: The setup can again be run without requiring administrator privileges
Fixed: applications crashed if no virtual mode (time, date or timezone) was selected.
Fixed: PE executable files containing a Bound Import table caused a crash of the application.
Fixed: Link checksum in PE files are now recalculated whenever the files are altered (this only occurs in static injection mode).
Fixed: Allows the resident injector mode on Windows>=NT
Fixed: The setup now kills the resident injector before copying files
Cracklock Manager Download
- The configuration dialog has been redesigned.New feature: you can create a shortcut on the desktop that will start the application with Cracklock loader. (There is a hotlink in the configuration dialog to create the shortcut).
New feature: there is now a Setting window available from the Manager that allows you to configure general settings for Cracklock. It contains the following options:
Add/remove Cracklock to the PATH environment variable (so that an application can find CLKERN.DLL if it uses static injection)
An option to copy CLKERN.dll to the folder of each application. Usefull if you use static injection and you don't want Cracklock to be in the PATH environment variable.
Activate system-wide injection by launching a small application at logon that is responsible for injecting Cracklock's DLL in every process.
Activate system-wide injection using AppInitDll (requires admin rights).
Install/uninstall the shell-extension for Windows explorer (requires admin rights).
Small bugs fixed in the manager and in the installation.
The configuration dialog has been redesigned (Note that some messages have not been translated in other languages yet).
The manager's list contains new columns showing the date, time and timezone selected for each application.

Fixed: the loader injection method (MCL.EXE) now works again. With this method, it is not necessary to alter any executable file to activate Cracklock.
Fixed: the loader MCL.exe now parses correctly its command line parameters. It is now possible to load an application with optional command line parameters with the syntax 'MCL.EXE APP.EXE APP_PARAMETERS'
Fixed: the system-wide option (when the system time is changed for real instead of being virtualized) did not work properly.
Several minor bugs have been fixed.
Setup: new option to decide whether to install a system-wide injector resident in memory (CLINJECT.exe launched at the logon or CLKERN.DLL loaded as an AppInit DLL)
Update: CLKERN.dll has been updated to take into account new win32 kernel functions that have been introduced in recent Windows updates
Internal: PEDUMP replaced by DUMPBIN in the toolchain.
A new example is now added automatically to the list of managed applications: it allows you to test Cracklock on the Windows control panel date/time applet.
Internal: the Makefiles that were used to compile the sources are now replaced by a Visual Studio project. MSBuild is now used instead of GNU make.
Internal: the new 'secure' versions of the string functions from the standard C library are now used. This protects Cracklock from potential buffer overflow attacks.
Fixed: applications configurations are now stored at the user level instead of the machine level (this permits to use Cracklock on a public computer)
Internal fix: the make build system is used in place of the Perl script files. Visual Studio Toolkit 2003 is used to compile the C++ sources.
Fixed: size of tab sheet title
Fixed: keyboard shortcurs in the manager
Feature: drag & drop is now allowed in the manager
Fixed: selecting a language un the manager now affects the shell extension with no need to restart the Windows explorer
