Quartus II will not complete install Have tried 7 times.

Hello all,

Recently I received my DE0 Nano board and am thrilled to get up and running with it. Only I am having a huge issue with the Quartus II software. For whatever reason it will not complete an installation. I have tried 3 versions of the software, versions 10, 11, and 13. My first three attempts were all versions of the default provided file, which I believe is version 13. What happens is that when the installation starts and tracks progress it never completes past 99%. It just remains there, stuck. I can expand/collapse the family device selection tool and click/drag the menu. I have yet to get a "Did not respond" error so that tells me that the installer is running by not completing or closing out the installation. Currently I am in the middle of my eighth attempt at installing. Some relevant information...Windows 7 64-bit, no active anti-virus or firewall during install (not that I think that would interfer with the install since it's already downloaded). So I am really at a loss for what to do about actually getting the software up and running. Any help is greatly appreciated.
