SQL 2008 R2 setup.exe does nothing

[scottcabral1979]

I have a Windows 7 64 bit machine running SQL Server 2008 Enterprise.

I would like to upgrade it to SQL Server 2008 R2 Enterprise. I loaded the media on the machine, but when i double click on the setup.exe, it displays a command box for a split second, goes away, and then nothing happens.

I tried rebooting the box, running as Administrator (by the way, I am part of local Admin group on this box), but nothing happens when I double click on setup.exe.

I have used this same media on other machines and it works fine.

Are there any logs that I can check to see what may be causing the issue?

thanks
scott
