Word 2003 Dialogue Box "System Error &H80040111 (-2147221231). Classfactory cannot supply requested class"

I recently upgraded from Office 2003 to Office 2010, and then uninstalled 2010 and reinstalled Office 2003 because of formatting issues with our documents.

After reinstalling Office 2003 Word, when I attempt to use one of the vba plug-ins (Infoware Document Assembly Tool), I receive the following error:

"System Error &H80040111 (-2147221231). Classfactory cannot supply requested class"

1: Has anyone encountered this error before?
2: How would I start troubleshooting this?

OS: Windows XP SP3
Terminal Type: Connects to Server 2008
I have completely removed the plug-in, office suite, and then reinstalled them.
Virus scan with Vipre showed no issues

If the plugin is what's crashing then it's probably referencing the wrong version of Outlook so you should do this

Uninstall the plugin and Outlook 2010 completely (using CCleaner, etc)
Reinstall 2003
Reinstall plugin

Thanks :)

I'll give that a try when on site this Friday.

I am thinking that possibly reinstalling 2010 and then removing it using the above tools might be useful as well in case any files got left behind.
I attempted all the fixes suggested, and it seems that some other components were upgraded along with the the office 2010 install. It was faster to reinstall windows on the machine than to dig and find out what was causing the error.

Another note is that other 3rd party application started complaining about not being able to determine the Microsoft word version after the Microsoft Office 2010 uninstaller was run and office 2003 was put back on.

Thank for all the help :)
do you use OWC by any chance? I ran into the same issue (with Office 2003) when I tried downgrading my OWC10.dll and OWC11.dll from the "security patched" versions to the versions that Microsoft has available on their website.
