It's something like this. I got Polish Windows 7.
The translate version is :
przestal dzialac - stopped working
Trwa wyszukiwanie... - Windows is searching for solution to solve the problem. <- I think it's smting like this :P

And if it helps - I tried to instal the vcredist_x64(Microsoft Visual C++ 2005 SP1) file from the RF folder but.. it want to install the file od hard-disk D:... AND I DON'T HAVE D, I have only C:..
Tried to download newer version, like C++ 2008. And it installed somewhere on C: but, the game's still not working ;/ Tried x86 too. Didn't work. :confused:
Don't know what to do.:(
