long time lurker first post lol this is so frustrating. Im trying to update teh graphics driver on my home-built tower, and teh official installer fails immediately:

Windows Update
We couldn't complete the updates.
Undoing changes. Don't turn off your computer.
Error code: 0x800f0922
"Not compatible with this version of Windows." Windows Update says Im fully up to date. the Catalyst Display Driver page supports Windows Vista x64... is the installer checking something besides the OS version? I feel like Im missing something obvious. I even tried downloading it on another computer and copying it over, just in case the file was corrupted... same error, same instant failure. I am honestly running out of ideas. thx in advance!!
