Are games compatible between steam on Windows Vista and Windows 7?

I just updated from Windows Vista Home Premium (32bit) to Windows 7 Professional(64bit). When I did this I copied over my steam apps folder to an external hardrive and then copied it to the new OS. Now all my steam games need to update and some, such as Crysis 2 and Bioshock won't work at all.



Crysis specifically says,"activation launcher has stopped working" Please help meAre games compatible between steam on Windows Vista and Windows 7?
Virtually anything that will run on Vista will run on 7. What you need to do is this: On each game in the library, right click it and choose 'properties' from the context menu. Next, click the 'local files' tab. On that tab click the 'verify integrity of file cache' button. Do that for each game in turn and it will repair the game, automatically downloading any necessary files. Only do this on one game at a time. I have transferred my games this way, it does work.

Because you've installed the 64 bit version of Windows you need to have copied your folder from C:\Program Files\Steam in Vista to C:\Program Files (x86)\Steam in Windows 7 x64. If you have copied it to Program Files instead then move it to Program Files (x86) - close Steam down first.Are games compatible between steam on Windows Vista and Windows 7?
You need to put them on your internal drive, you can't just share them on one external drive, because there are certain settings that are saved because of your OS. That's why you get that message with Crysis. You can redownload your stuff free on your other PC via Steam, and then you can register your computer as one of your allowed devices to run software.
