Interface not registered in Outlook 2003

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

  1. Close all running Office applications, like Word 2003, Outlook 2003
  2. Click on Start, click on Run
  3. Enter the following line: Regsvr32.exe %Windir%\System32\Ole32.dll
  4. 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

    Thank you sir, I had contacted our help desk and had done the Word reinstall, Outlook repair and reinstall. Next was Outlook complete installation. No need, Word works fine.

    If only you had answer to why Windows Media Player 11 will not run, that would be very helpful. I have read all the postings, checked every registry key mentioned, fixed all the ownership errors, keys that cannot be accessed, etc. – nothing has worked thus far.

    Let mek know if you can help, I can send logs.

    Thanks again.

  4. Hello Y’all,
    Am I smiling or what? Sent 2 test mails and so far no error messages so looks like you helped me fix both problems. Thank you so much.

  5. Thank you I hope it works. MS help info. is not designed to to help nongeeks and those who still learning their way around. Now they are charging for email help requests. I have another mail problem so may be back.
