Seeing that you downloaded VC,
It is highly likely that you applied a cracked exe file.
VCMP will only run on gta-vc.exe which is v1.0
Re-install VC and try using it with a different crack or no crack at all.
If it is not the crack that is causing the problem,
Download another version of VC.
PS. All VC installations should install v1.0 ... I think.
