I think that I recently had a problem very similar to yours, Mark. Before the June 30 discount cutoff date, I downloaded the new Nik 4 collection. I had been an old version of the free Google Nik collection. Coincidentally, I also could not get Silver Efix to start. When I attempted to get Color Efix to start, I received a message to input my license number. After I entered the number, Silver Efex worked normally.
Thanks, Joe. I don't have a license number - it is a very old a free version. I don't use it often.
