If you look in your %TEMP% directory, there should be more log files near the one you attached (most of the filename will be the same).

Could you zip them up and attach all of them here? I think there's some information in one of the others that I'll need to see.

Also, you shouldn't have to run this installer as admin. If you are not planning to install for all users on your machine (and according to the log, you did not select that option), then it may work better if you just run it as yourself.
