Every time I try and open CS5 I get a message saying that a file - MSVCP100.dll is missing. Once I've tried to delete this message approx 20 times the message finally disappears and I can open Photoshop. Obviously the file isn't missing, but is being troublesome to read. I have run the Microsoft patches to fix this problem, and have also run a commercial dll file fixer with no success. I have even copied the relevant file from Windows disc onto my laptop but it still doesn't want to work. It is looking like CS5 for some reason cannot allways recognise the file. Is there a fix that I can use for this?
