VB How far backwards compatible?

[pmorrisseau]

I have written a fairly substantial, multi-page Excel document with a pretty high number of macros, forms, and external access calls using MATLAB and Rhinoceros 3D modelling software in MO 11.0. I have used library references:
- VB For App's
- ME 11.0 Object Library
- OLE Automation
- MO 11.0 Object Library
- M Forms 2.0 Object Library
- Ref Edit Control
- and Excllink for MATLAB

I am wondering if anyone knows off hand, what is the earliest version of Excel that will handle my macros. . .

Thanks in advance for the help.

Excel 2003 is the only guaranteed.

You should develop it in the earliest deployment version of all products if you want it backwards compatible.
