Games for Windows Live Install Fail, error 0x800b0003

DiRT 3, among other games, requires GFWL to play. I've tried many solutions, but nothing has solved this install error and until it is fixed I can't play any games. I have all critical, important and optional windows updates. I'm running Windows 7 Ultimate 64-bit. The weird part is that these games used to work. I rebuilt my computer recently with an ssd boot drive, but the os is the same and so is all the other hardware. So really it should be the same computer, I really don't understand how to solve this problem. I've tried some hotfixes recommended for this error but it seems that this error code is very generic so it's hard to find advice that actually relates. The only forums that discuss my specific issue recommend installing this update:
Update for Windows Server 2003 x64 Edition (KB938759)

that update is for xp and doesn't want to work on my computer. running it once says i need to be admin. of course, i am. so I run as admin and it says not enough space on the drive or something like that. there are gb's of space on the boot drive and my storage drive, so that doesn't seem to want to work.

another forum says that this error code is only for xp and that windows vista should not experience this issue (found here: http://support.microsoft.com/kb/960554) I've tried downloading the installer from various locations, but the same thing happens every time.

my buddy has GFWL working just fine, i'm wondering if it's specific to windows 7 ultimate. either way, i am totally out of ideas. any ideas you could offer would be a great help.

thanks a lot,

Found another small detail. So I try to run the installer. It looks like it's downloading, then it fails and gives me the error code: 0x800b0003. Try the support button, and you get a dead link on microsoft's website. Very nice. Open the log files and here's what I find. Setupexe.txt says that the installer downloaded correctly, but as soon as the install was initialized it failed. xliveinstall.txt tells a similar story. Checks the disk space, then downloads the installer. The download finishes, but then it says that the xliveredist.msi was not signed correctly, which means it failed to validate and hence i get an error code. But the xliveredist.msi is the installer file that IT downloaded. So it's failing to validate it's own files? I've tried redownloading the installer and I get the same thing. Very very strange. I'm starting to wonder if it's a registry thing. It was a fluke that happened once, but now it's destined to happen every time because its sitting on my computer somewhere. I really hope someone else has something to contribute.

same problem here, and I'm on pro, so its not restricted to ultimate. Anyone ever find a solution?
