Hi Helen,

"don't run" means it never even flashes on the task bar. It never
shows up in processes under task manager.

As I said the main form is created first in the dpr but it's OnCreate
method never fires (Application.CreateForm(TfrmMain, frmMain);).

I'm not sure this is related to IBO. I just can't think of anything
else that's unique to these 2 applications.

There are no hard coded database paths. I don't know anything about
the use of MS C or C++ stuff; these are Delphi 7 apps.

Also, these applications are running on hundreds of computers so the
problem has to be machine specific. I just don't have a clue what to
look for.
