After upgrading to the recent Win 10 operating system, I get errors trying to open programs.  First cg.dll was not found, so, I supplied the file to the operating system.  Next, I tried to open the program and I get: The program can't start because cgGL.dll is missing from your computer.  I can't find this file to supply it.  I'm afraid if I did, something else would be missing.  So, I can't find the solution on the Microsoft site or anywhere else.  If you have a solution, write me:  *** Email address is removed for privacy ***

Thanks         PS:  I'm trying to open Photoshop, it is not in the product category and, Movie Maker is not my problem product.
