When I try upgrading my 7.0 Vegas install to 7.0e, I get the following error :

"Please make sure you have local system administrator privileges on this system"

and the installation fails.

The install box says :

extracting \mediamgr\mediamgr3_enu.msi

I have a full purchased and legal copy of Vegas 7.0 and DVDA. In the past, I have upgraded on this machine (and others) with no issues.

Any thoughts on what is wrong? I am logged on as the computer administrator for my PC.

Thanks in advance...
