Explorer.EXE - Cannot verify digital signature
I've recently ran the upgrade for the Windows 7 RC from vista business. Now all of the sudden I cannot run many of my programs (especially those that need UAC) because Windows cannot verify the digital signature for this file.
(X)
Windows cannot verify the digital signature for this file. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source.
[OK]
This happens with Explorer.EXE when I try to right click on Computer->Manage. It happens with OptionalFeatures.exe when I try to Enable/Disable Windows features from the Control Panel.
I had the Norton Labs UAC installed on Vista. Perhaps that's the problem? Any help is greatly appreciated!
