Even after I took full ownership of the C:\Windows\winsxs\ directory and add the files Kirk posted and said it would fix this error
Error 1603. Error 1310.Error writing to file: C:\Windows\winsxs\Manifests\x86_Microsoft.VC80.CRT_1fc8b3b9a1e18e3b_8.0.50727.762_x-ww_6b128700.manifest. Verify that you have access to that directory."
I still get it, for lots of people it worked, but still not for me
