The exe file for the demo is : 458,445 kb
Operating system : 7..though because of a virus I've lost many system files in the process.
The error message : Download verification failed: Cannot open archive.
I did try to install the game first and it works perfectly. But then I couldn't install the patch because of that error message... Is it possible to use the patch installer after extracting the game? I guess I'll try that.
edit+
It works
