Has anybody seen this before?

When I issue CreateObject("Word.Application"), I get the following error:

"Class Factory cannot supply requested class"

CreateObject("Excel.Application") works fine. I'm using Office 2003 and have been for a while now. This seems to be happening since I updated VFP9 with SP1 on Windows XP SP2.

It's on my pc at home. I haven't updated to SP1 here at work yet - different OS anyway (Win2k sp4).

I'm thinking I'll try reinstalling office, but I'd rather not have to, of course, so if anybody knows what this is about, I'd appreciate any help.

Thanks
