Boot Camp drivers won't install on Windows 7

[Taquiq]

I have a late 2011 MacBook Pro, OS X Yosemite 10.10.2. I installed Windows 7 (64-bit) via Boot Camp and it worked fine, the problem now is that the drivers I downloaded (5.1.5621) will not install. It says to check the bit-version or whatever, x86 or x64. Then I tried to troubleshoot the BootCamp.msi file in Drivers/Apple but this happens... (see attachment). Thanks for the help.

Try this - I'm having trouble with sounds through Outlook at the moment, though nothing major.

Did you download the drivers manually from the Apple website? If so, try letting Boot Camp Assistant download the drivers for you and use those. Maybe you have a slightly different build from the one your machine needs, BCA should always get the right build for you.
