Run As Date doesn't require any installation process or additional DLL files.
In order to start using it, simply copy the executable file (Run As Date.exe) to any folder you like, and run it.
Starting from version 1.03, when the 'Immediate Mode' is turned on, Run As Date inject the date/time immediately when the process starts, without waiting to the kernel loading.

Win RAR's native file type, RAR, is a proprietary file archive format.
