Solved Reluctant File Association for .mdi ???

Microsoft Office Document Imaging is running perfectly with one exception! I cannot open .mdi files by double clicking them. Although if I open the Office Tool first, then I can quite happily do a File Open sequence and use the .mdi file normally.

The .mdi file extension refuses to allow itself to be associated with mspview.exe (the correct executable file) - even when I try to do it via Default Progams using the built-in administrator account. No helpful error message - just no response (I AM able to associate .mdi with other (incorrect) exe files - so it seems to be mspview.exe that Vista has taken a dislike to for some reason.

It was working ok until I uninstalled MS Office 2003. I DID have both Office 2003 & 2007 installed - but the older version was redundant.

I see no reason why Vista should block this file association - unless I have a Registry issue potentially? (And yes - I have done several restarts)

I can of course do a System Restore (hopefully) but I wondered if anyone had any ideas why I'm having problems? Alternatively, I can re-install Office 2007 completely but that seems to be a bit of a sledgehammer approach.

Any thoughts gratefully received

Cheers

Just for info - I have done a successful System Restore and .mdi fles now open on double click as expected! So I guess this is something to do with Office 2003/2007 potentially?

I'm not short of disk space - so I'm going to leave well alone and not uninstall 2003 again! That is unless anyone has any theories that I could check out ? In which case I'm happy to re-create the earlier situation.

Sorry if this seems a bit impatient - but I thought this was such an obscure issue that not many folks would have come across it and decided a Restore was the easy way out.

Yep, Vista has problems when there are multiple versions of Office installed.

You need to uninstall both (the latest one first, I believe) and then reinstall the one you want to keep.

Thanks Ed

Just as I suspected!!! Guess I'll be getting a new machine and "suffering" 7 soon so I'll just leave well alone here now! If it ain't broke - don't fix it as they say!
