CUDA Installer hangs

I’m trying to install CUDA 2.1 on a Core i7/GTX280 machine running Vista Business 64-bit.
The driver and SDK installs without a hitch, but the toolkit installer only displays “NVIDIA CUDA Toolkit is configuring your new software installation.” and hangs infinitely.

This seems to be the same problem as reported in, but rebooting does not help.

I am having the identical problem with a Core i7/GTX285 running Vista 64 as well.
