>>>Ramon, thanks for the reply. I guess I am confused/concerned because on page 831 of the VB Programmer's Guide it lists the following files that are classified as runtime files and must be distributed:
>>> msvbbm60.dll, stdole2.tlb, oleaut32.dll, olepro32.dll, comcat.dll,
>>> asyncfilt.dll, ctl3d32.dll.

Here's a URL that SAYS it does VB5:

Don't use VB, so I really don't care!
