Please Help - nmorenu.dll won't register

I have done everything I know how to do and cannot get nmorenu.dll to
register.  Using Delphi 3.0 C/S and Install shield Express 2.0.  All other
.dll and .ocx files self register with no problems.  I've read every web
page and new article I can find and cannot find a solution that will work
for this.  When you install the app it simply says "Failed to self register
c:\windows\system\nmorenu.dll".

If you've had this problem or just know what to do please let me know.

You can reach me at motives.nws.net.

Thanks in advance,
Shawn Looney
