C:\windows\system32

[Bob]

In running the directx diagnostics (dxdiag), I get a
message that says "mfc42.dll has been incorrectly
installed in windows and should be deleted"

I'm a little reluctant to delete this file as I'm not
sure what it does or what will happen if I do.

Any information and advice will be appreciated.

Thanks

Hi,

Mfc42.dll belongs in the C:\Windows\system32 directory, not under
C:\Windows. If it is there, it should be migrated to the system32 folder.

The file (mfc42.dll) is a system protected file. If you delete it,
another copy will immediately appear in its place. Make sure it's
placed in c:\windows\system32. It also may be that the file is not
registered properly. Try this from a command prompt:

regsvr32.exe mfc42.dll

Make sure there is a space between the command and the dll.

A message from a diag program doesn't necessarily mean anything is wrong
with your PC. What _is_ not working on your PC?
