teceem: Nope, install Galaxy wherever you like.
mastrervg: Here is an update. I got them to work by installing them through the offline installers
So there seems like some kind of bug or server issue that is causing problems with Galaxy right now. I assume the games were getting stuck during installation but still consuming bandwidth?
I just had this happen to me yesterday too. Some have stated if you leave it long enough they will complete but I have not confirmed that. Anyway, I'll check the bug reports tonight and If I don't see one for this I'll submit a report on mantis.
Thanks.
