I do that routinely and have seen no problems. I have Win 7 64-bit Home
Premium and most of my files (I use VBA a lot) are Win XP with Excel 2002
and 2007. HTH Otto

Hi
I would appreciate any practical advice.....
I've never changed o/s before and I'm considering buying Windows 7 Pro 64
bit but besides all the usual compatability problems I've read about with
any
brand new o/s I'm not able to determine whether:
1. vba apps written in Excel 2003 and WinXP Home 32 bit will run on any 64
bit system - either WinXP Pro or Win7 Pro
2. I can expect them to run natively in Win7 or if they can only run using
XP Mode.

Has anyone any practical experience?

T.I.A.
