Background:
My machine is running Win 98 with VB6 Pro and SP4.
I compiled the project and created a setup routine with Install Shield Express 2.13.

After running the setup on one user's machine who also had Win 98 with VB6/SP4 produced no problems when she ran the program.

After running the setup on another user's machine (a 486 with Win 95, no VB) caused the following problem when she tried to run my app:

Error 430 - "Class does not support automation or does not support expected interface."

Any ideas as to what could be causing this? Thanks for your help.
