Did a clean install of PPro CS4 on Vista 64 OK. Ran the 4.1 update - says it installed OK. Go to run CS4 and get error message - "Audio Filter Host.dll not found. Reinstalling may fix the problem" I reinstalled the OS , (formatting C drive), reinstalled CS4, update to 4.1 and get the same problem. I need to run 4.1 to be able to use my Matrox RTX2 card. Help please?
Did you run the update process from the program, or did you download manually and install from your hard drive?
