I just have the same problem I look on the internet for other users
with the same problems and there are plenty of them.

There are some answer on this subject like:
run the following command in run:
Regsvr32 C:\Windows\System32\MSRDO20.DLL
Regsvr32 C:\Windows\System32\OLE32.DLL

run the following text under the run command: Msiexec.exe /fm "GUID
for Office 2003 Product" (between the quotation marks give the
registery key). Office will install again but the problem stay.

Give permissions to appropriate users on the following key.
HKEY_Classes_Root\Word.Document\CurVer

Remove Normall.dot from the roaming profile.

Just remove all older versions from Office from the computer and
instal Office 2003 again.

The last solution that I read remove Office 2003 by hand from the
register of windows. So i did that after a restart from the computer
Office 2003 was completely from the computer. So I reinstall is again
but I get the same error again.

The computers are member of a domain on the background running a
exchange server 2003.
If a other log in the computer it have the same problem as the
standard user that always work on the computer.

All the updates from Windows and office are installed but the affect
are the same.

Do somebody have a idea of a solotion of this problem
