I run three versions of Excel on my machine without problems.
(though, I don't have xl 2003)

Each version should be installed in a separate folder and only
one version should be open at any time.
Also, do you have code in the workbook.open event?
If so, that could be contributing to the problem.

I have a workbook with macros that was developed using Excel 2000. It has
been working fine.
Recently, I have Excel 2003 installed in addition to Excel 2000. So there
are two versions of Excel on my computer.
Now when I open this workbook. I received an error message:

Runtime error -2147417848 (80010108)
Automation Error: The object invoked has disconnected from its client.

And Excel freezes.
Is having two versions of Excel causes this problem?
Can someone please help me resolve this?
Thanks!
