Intel INF Chipset installation stuck on Windows 7 64-Bit

Intel INF Chipset installation stuck on Windows 7 64-Bit

I am about to re-setup my system, running on a GigaByte GA-X58A-UD3R /
Core i7
I installed Windows 7 64-Bit and now downloaded the INF update utility
from the GigaByte website.
When running it, it installs a few things, then it says:
Installing Intel(R) 7500/5520/5500/X58 I/O Hub System Management Registers
- 342E
And then it just keeps installing and installing, but never comes to an
end. Waited for 10 minutes already. Rebooted. Safe mode. Tried it all.
What's wrong here?
