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 http://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.

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).

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 !

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.

Choose "Cracklock" from the list of applications in the Add/Remove programs applet of the Windows control panel.

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.

Start the manager (shortcut Cracklock Manager in start menu):

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).

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.

Select the program that you want to configure in the manager list. Click on the "Program" menu then on "Settings...":

This brings you the configuration dialog box:

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.

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.

Right-click on the executable file. A contextual menu appears:

In this menu, select "Properties". A window with several tabs show up, select the tab named Cracklock:

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.

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. <br> 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. <br> 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. <br> 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-time With 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.

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: "C:\PROGRAM FILES\Cracklock\MCL.EXE" C:\APP\APP.EXE [program_parameters] where "C:\PROGRAM FILES\Cracklock\MCL.EXE" is the full path to the MCL.EXE file installed in the Cracklock directory, C:\APP\APP.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.

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.
