Today I installed Design Premium CS5 successfully via download on my PC Win7(64). I want to install the fxg extensions for Photoshop and have downloaded the file from Adobe. When installing the file via Extension Manager, running as administrator, I get the message "you do not have the appropriate permissions required to perform this operation....etc" I am the only user on this machine and am administrator. On advice from a forum thread I downloaded the latest version of Extension Manager and installed it, with no joy.
I see in the forums that I am not the only one with this issue. Surely someone has an answer. Please?
