I am installing PowerPivot. I am installing into the 32 bit version of Excel and running Windows 7.

Here is the installation error I am getting.

An error occurred during in the installation of assembly Micorsoft VC80 CRT = "8.0 50727.6229 Publickkey Token = 1fc83b9a1e18e3b, processor architecture =x86, type=win32, please refer to help and support for more information. HRESULT:0x80070BC9.

What is wrong? Any help is appreciated. Would like to use PowerPivot but can't get past installation.
