flashpoint updates problem

[pagongski]

I cant update my copy of flashpoint (1985 cold crisis) to any of the new versions.
The game i got is not instalable, i mean, i got it on a zip and to run it unzipped it to a dir and all the files are there.
When i try to run any updater (even cracked ones) i get the message saying the game is not installed or is corrupt.

Isnt there some sort of registry patch to "fool" the updaters?

thanks.
