Hello,

I spent a multitude of hours today trying to solve the following problems with Office:
1) Could not print from Outlook - always got a script error on line 1343
2) Could not use Send To from Word or Excel and send the documents in Email
3) Could not use Word as the default Email editor

The usual error was "Interface not Registered".

I performed the Repair installation (no help), and also removed Office completely and reinstalled (no help).

(Note that my setup is Win2000 with Office XP)

After combing through all the postings/microsoft solutions(fantasies), and web info, I arrived at the following procedure that I would follow. This are in increasing difficulty and complexity:
1) regsvr32 C:\WINNT\SYSTEM32\OLE32.DLL
2) regsvr32 C:\WINNT\SYSTEM32\MSRDO20.DLL
3) Add a new profile using control panel - mail - profiles
4) Regclean from ZDNet
5) Repair windows installation
6) Reinstall windows

In my instance, after performing the first 2 steps all the problems were gone and everything works fine again (thus I did not have to perform steps 3-6). Other users reported that simply doing the re-registration did not fix their problem. For other users, I would suggest checking the problem after each step to see if it fixed it before proceeding to the next.
