I am trying to run a program that needs MFC42.DLL. I downloaded the dll from a site and put it in the system32 folder, but it still did not recognize it. I changed the permissions to be more lenient but that did not help either. So I found and used winetricks vcrun6 mfc42 After doing this I made a terrible mistake. To make sure that it really added MFC42.dll and was not still the file I downloaded from the internet I decided to delete MFC42.dll and rerun winetricks. But winetricks said that vcrun6 and mfc42 were already installed so they did nothing. Now I have no MFC42.DLL and I'm afraid my program would not recognize it if I did have one. What do I do?!? Thanks.
