Blender fails to initialize on a fresh Windows Vista 64 install HELP!

This is driving me insane. I keep getting "The application failed to initialize (0xc150002). I’ve tried installing the 32 and 64 bit versions of Blender and reinstalled Vista. I keep getting the error. Anyone know how to get past this?

In case you don’t have this already, install the MS Visual C++ package

Thanks so much!
