When you have set Word 2003 as your default e-mail editor, you might get the error “Interface not registered” when trying to send an email. You are still able to send messages with the Outlook editor set.
To solve the problem which causes the “Interface not registered“-error, do the following
- Close all running Office applications, like Word 2003, Outlook 2003
- Click on Start, click on Run
- Enter the following line: Regsvr32.exe %Windir%\System32\Ole32.dll
- Press enter to apply
Sending mail with Word 2003 as default editor in Outlook 2003 should now work again
If the line “Regsvr32.exe %Windir%\System32\Ole32.dll” causes an error, try the following line: “Regsvr32.exe Ole32.dll“
