Recently, I've been receiving all kinds of error messages regarding the riched20.dll file in the c:\windows\system32 directory. I want to repair/replace it, but Windows Vista will not let me rename or move the file even with administrator permission.
One recent error when trying to run a nVidia Forceware driver upgrade I get is "The procedure entry point RichEdit10ANSIWndProc could not be located in the dynamic link library RICHED20.dll."
I also try to unregister the .dll but it won't let me do that telling me it can't find the entry point. I've Googled this to death and can't find a fix. Please help!!
