Doesn't work on Vista 32 bit.
Here is a much easier program, created in notepad:
1. Create a new text file.
2. Copy paste:
C:\Windows\System32\taskkill.exe /f /im vc-mp.exe
3. Save and rename file to kill_vcmp.bat.
4. Run.
Info: should work properly on Vista and 7 (32 bits), unsure about XP. Locate "taskkill.exe" on your hard drive, and put the right path to it into kill_vcmp.bat file.
I am using this program, but with gta-vc.exe parameter, useful when game freezes or when I want to quit game, while it's minimized in the taskbar.
