An important VBA help file, Veenlr3.hlp is sometimes missing form the PC, if they didn't run the "full" install. The file is on the Office CD in:

\OS\MSAPPS\VBA\

You should be able to just copy it off the disk into:

C:\Program Files\Common Files\Microsoft Shared\VBA\

then right-click it, select properties, and un-check the Read-Only box (since it came from a CD).

I've also uploaded the file to my web site, you can get it from:

http://www.wvmitchell.com/files/VEENLR3.HLP

It's about 1.1 Megs, so it might take a while, but it's there if you can't find the CD. Note that this URL is case-sensitive because I'm on a UNIX server.
