I have downloaded the newest nVidia drivers for the unibody MacBook (186.03 WQHL) from their website numerous times now, and I simply cannot get it to install in Windows 7 running in Boot Camp. It says that the executable is corrupt, although I know that there are people here that have been able to install it successfully. Another weird occurrence is that I cannot even get it to save to my Windows 7 installation. The download will complete, and then the file will just disappear. I've had to download it on other machines and copy/run it from there, still with no success. Any ideas?
