I have Windows 7 64-bit, have plenty of disk space, and have also tried running as Administrator
In the log file I have near the failure(I believe)...

I even tried manually installing vcredist_x86_vc2008.exe in the hopes that the installer would detect it and skip it. But now I see above that it was deemed as a Success. This is just a trial version if that makes a difference.
