I looked here in Seven Forums
for this known error and have found some threads about it. However, none of them had a solution of any kind, and that's why I'm creating this new thread. I am having the exact same issue, and I hope to find a solution because it's really annoying by now.
I have had this error in more than two games, so that's why I think this is not a specific game error no longer. What's more strange is that for test purposes, I tried installing again a game I had previous installed succesfully (Assassins Creed II), and this second time, I had this error message.
It happens when the installation is supposed to begin. When the installation executes a Setup.exe, Installer.exe or some file like this one, the main installation file of the game, it stops immediately with the following error message:
The version of this file is not compatible with version of Windows you're running. Check your computer's system information to see whether you need an x86 (32 bit) or x64 (64 bit) version of the program, and then contact the software publisher.
I had installed before Assassins Creed II and FIFA2010, and both went fine. Then I tried installing, other day, Arkham Asylum and Left4Dead 2. On both of them, I had this error. Then I tried installing, again, FIFA2010 and Assassins Creed II so I could prove that the previous games were damaged or something, but I had again this error and now with games I had just the day before installed.
Then to go further, I downloaded on the web image files for those games (ISO), just to make sure there was something wrong with the computer, not the disc itself. I emulated the ISO files, and the .exe files inside it such as Installer or Setup.exe, when I double-click them, they come up with the same error message stated before.
I really don't know what happened in just one day that messed up my system. What I can assure is that is NOT a disc/image corruption of some kind.
I tried a lot of things, none of them worked. So I literally BEG for a solution. The bottom line is: Windows 7 Ultimate 64-bit (x64) is not accepting to install game's .exe files from disc or ISO file
