iTunes not compatible with iPod Touch 4th gen (problem with Windows 64 bit)

So I've been trying for about a month or so to sync my iPod Touch to iTunes but ever since i updated it to iTunes 11 it has been saying that i need to uninstall it and install the 64 bit version. I've done that twice this week alone and its still not working, saying again that i need the 64 bit which I already have. I've ended up completely erasing previous iTunes data to see if that would help, but that just ended up being more hassle. I don't think its just my iPod, because it refuses to sync my iPad 2 manually as well.

Please help me, i'm at my wits end.
