Visual Studio - prompts are in German

When I build any new VC++ application, the File Save dialog, Print dialog, etc. prompts are in German.
e.g. "Save Changes to Untitled" becomes "Anderung in Unbenannt speichem" ... "untitled.txt" becomes "Unbenannt.txt "
Did I accidently select this somewhere ? or has a dll been replaced by a German version ? ...
(This is not a project setting since it affects any project I build even freshly downloaded Microsoft sample programs)
Any help to get this back into English would be much appreciated.

 

The answer ...

This was caused by the file mfc42loc.dll being present in c:\windows\system ... it was the german language version. For English systems this file should not be present.

It is interesting to delete this file since any application that uses mfc42.dll also loads this file and locks it against deletion. So need to come up in DOS mode to delete it.
