I ran the direct download installer, and I had the same result. Wasted hour. X(. Yes I have complete admin priveleges on my comp. It's only certain files in the installer that are not writing. the actual error message is, "Error opening the file for writing." I'm going to try and completely shut down my system and restart and hopefully that will work. But I have to go to work now. Please someone more tech savvy than me, figure this out!
