Re: Games for Windows Live not installing (error code 0x800b0100)
Actually, forget everything - it was a bad download. Which is funny, because I downloaded and tried several copies of the installer before posting here, just to be sure, but now I tried downloading a new one, which suddenly worked, even though the old ones still don't...
Anyway, it was more or less my bad. But still, several thanks to everyone in here for the help, sorry to be wasting your time like this ^^'
