I uninstalled a virus software and starting getting this error in Outlook. I

have completed the following steps trying to get this problem corrected.

1. Open Outlook in Safe Mode and enabled and disabled on Add-In's

2. Defrag drive

3. Run Check Disk

4. Removed all entries in registry having to do with old virus software

5. Purchased and ran a registry cleaner

6. Uninstalled and reinstalled Outlook

I have run out of things to try. Anyone have in suggestions?

Did you re-register redemption.dll with regsvr32.exe?

What is the exact error?

Where does your code run (standalone exe, COM add-in, etc)?
