Here is some info if this is the type of error message you receive:

I think the best way to explain this error message is to list an example and
then walk you through the troubleshooting logic I'd use.**Example**:  The
LOADWC.EXE file is linked to missing export SHLWAPI.DLL:wnsprintfA

File one is expecting file number two to be able to do something which it
cannot do.  This generally means the second file was replaced with an older
version which doesn't contain the functionality that first file was
expecting to find.  There's a possibility file number two is corrupt or
missing but most likely an older version file is the cause.  In either case,
replace *your* file two with a current (or more current) version.  For help
finding a replacement file, go here and do a search:
http://support.microsoft.com/servicedesks/fileversion/dllinfo.asp

Do a search on *your* file two and be sure to include the file extension
(.dll).  Once the results appear, locate the version of file two that your
PC is using and work up the list.  When you click on the more information
link, you will find what product(s) that version of the .dll is contained
in.  This may give you a clue as to what version of the file should be
there.  For example, you have version 5.0.2614.3500 of the shlwapi.dll on
file and by checking the list of files, you find this version comes with
W98SE.  Going up the list, you find version 5.50.4134.600 is contained in IE
5.50.  If you had updated your browser to IE5.5, there's the problem--the
correct version of shlwapi.dll got overwritten by the copy with comes with
W98SE.

Finally, the troubleshooting information above centers on file two since it
should most likely be the source of the problem; however, file one could be
an incorrect version or it might be corrupt.
