Bootcamp 3.3 and Safari, Quicktime, etc. won't install.

[SelrahcRenyar]

I just installed Windows 7 on a partition, and everything ran smoothly. I installed the drivers from the setup disk that came with my 2010 MBP, and "apple software update" was installed as well. It prompted me to update to bootcamp 3.3, and I checked this option as well as quicktime, safari, itunes, etc. It told me that I had to reboot for these changes to take effect. After the reboot, they were still not installed, and I was prompted to update bootcamp again. I've combed the internet for solutions, to no avail. I've checked to see if I have any display adapters installed, as that could be a problem, but I don't. Any ideas on what could be the source of the problem? Thanks.
