Sorry, apparently I did not communicate well.

The developer should get a copy of Excel8.olb or Excel9.olb and save it on
his/her computer. Then reference this in the Autocad macro file just before
saving, instead of their version of the Excel library. Redistribute this
copy to the user. Com will re-route the reference to the users version of
the Excel library just fine, as long the version of Excel is not older than
the version the developer referenced when the file was saved.

I tried this with AutoCAD 2002 and it worked just fine, just as it does in
VB6.

The user doesn't save the file with updated references in VB as Bradley
describes.

I would still approach it this way. Get a copy of someones older Excel
type
library file called Excel8.olb or Excel9.olb. Put it on your computer
(you
don't need to do anything with it, just get a copy of it) and reference
it
before you save the Autocad file. This should work fine for your users.
(I
haven't tried this in VBA but have done it many times in VB....I think
it
should work fine in VBA, as well)

I like that, but the office computer is up to date and only references
the
latest version, user's home computer's usually have older versions.
Also,
once the program is run on a newer version, that seems to become the
reference and won't run on older versions.
Since I'm a newbie, I'll have to read up on this "binding" that I have
skipped over so much. Thanks for the help.

Late binding WILL cause a perforance hit.....depending on your
particular
application, this may or may not be acceptable. I would early bind
and
reference an earlier version of Excel (like 97 or 2000, assuming you
don't
use any features not supported by these apps). If the user has a
new
version of Excel you will be fine.

Use late binding - don't have a reference to excel.

I often run Excel VBA applications from AutoCAD, but the
reference
to
Excel
is particular to the company's computer that I use. When it is
run
on
another computer with a different version of Excel, the
application
fails.
Is there a way to check for Excel versions and apply the correct
application
reference?
