Just went to install crysis today after a long while and it wont install. The autorun comes up, clicking install closes it and nothing else happens. I tried running setup.exe form the root but it comes up "this version of the file is not compatable with the version of windows you're running", I'm on W7 64. Looking around on google no one else has trouble running crysis on windows7 64 bit. I tried running crysis.msi, but it must need to be run together with the installer as it comes up with a cd key tool error. Any ideas? Is there something I need to download to fix this?
