I was about to apply the license to Symantec Backup Exec 2010 R2 onto a trail version installation that's been working like a charm for the past 2-3 weeks. I am unable to apply the license though due to thr fact that I receive an access denied to the symcinstall file. I tried to uninstall through programs and features; same thing. I even went to the registry area for this and again, I receive an access denied. I gave this program files directory full access rights to the very T and am still receiving this error of not be able to access. I tried a different profile, same thing. This installation has become corruptted and more worse, I am unable to apply the license to continue using this product. Does anyone have any suggestions?
