Man, I don't know how Bob Scott figured that out, but I may be contributing to the status project. I got rid of the input.inf file, but I also have a whole host of DLL files that are showing the exact same "FILE LOCKED WITH ONLY READERS" error in a repeating pattern:
C:\Windows\System32\opengl32.dll, d3d9.dll,ddraw.dll
Any solve for the dlls that it as simple as the input.INF?
