Outlook gives me an error after EML to Outlook deinstallation

Attention! This problem was actual for the very first versions of our tool. All new versions are working independent.

Please help me to solve the issue with uninstallation of Outlook Import Wizard demo. I have uninstalled the utility for importing eml into outlook and MS Outlook starts display a message about removed add-in.

The Original Issue and Question:

After I uninstalled the Eml to Outlook importing tool, every time start up Outlook 2007, it gives me an error message: The Add-in “RDO Helper Outlook Extension” (C:\Program Files(x86)\Outlook Import Wizard\oenimport.dll) cannot be loaded and has been disabled by Outlook. Please contact Add-in manufacturer for an update. If no update is available, please uninstall the Add-in.

I tried reinstalling and uninstalling but it no helps. Please provide me with a removal solution.


(A) It is possible that you have tried to remove the Outlook Import Wizard when the Microsoft Outlook was executed, so the was not removed from Outlook references. You can reboot the computer and the installer could complete the removal.

(B) As a variant, you can execute this command under Outlook Import Wizard install directory using the command prompt to unregister the add-in:
regsvr32 /u oenimport.dll

(C) Or you can do the following:

  1. Reboot the computer (Please don’t run the MS Outlook)
  2. Install the Outlook Import Wizard if it is uninstalled (Please don’t run the installed OIW)
  3. Remove the Outlook Import Wizard
  4. Reboot the computer
