I have a VBA application written in Excel 2000. The appl contains several
forms and custom menus.

I tried running the appl on Excel 2003, but got errors.

(I can't remember exactly what the errors read, but Excel 2003 gave me
warning messages saying it didn't recognize some components or code. And,
the code would not compile.)

I can run an earlier version of the same Excel 2000 VBA appl on the same
Excel 2003 PC with no problems. But this earlier version has no forms and
no custom menus, just macros & custom functions.

I believe the problem is the Excel 2003 object libraries are different from
the Excel 2000 object libraries. And, I'll need to set references in Excel
2003 to the Excel 2000 object libraries.

These are the libraries I suspect that I have to set references for:
- Microsoft Office 9.0 Object Library (MSO9.DLL)
- Microsoft Excel 9.0 Object Library (Excel9.OLB)

(If they are even listed in Excel 2003. I didn't look, and the PC is at a
different location. I'll be trying to get the appl working on Wed, Aug 9.
But, I'll be at that other location tomorrow, Tue, Aug 8th, and will have
some brief time available on that Excel 2003 PC.)

Am I barking up the right tree, or just howling at the moon?

Any confirmation, hints, traps, or other possibilities would be appreciated.


Also, these are the object libraries that are referenced in Excel 2000 where
the appl was developed:

Visual Basic For Applications (VBE6.DLL)
Microsoft Excel 9.0 Object Library (Excel9.OLB)
OLE Automation (stdole2.tlb)
Microsoft Forms 2.0 Object Library (FM20.DLL)
Microsoft Office 9.0 Object Library (MSO9.DLL)
