Start by reinstalling the program with sufficient user privileges and also check your windows Media player components and system CoDecs. They may require reinstalling, too.
Did Tim's link help you?
I am really hoping that you can help me out with this. The plugin failed to load has happened for a while. I read that it could be because of not having windows 10 installed. I upgraded to windows 10 with no difference. now a second problem occurs and the program will not even load.
I have tried clean installs multiple times. I have followed all of the advice I have been able to find on the forum and I am at my wits end.
I use CS6 Master Collection.
