I recently uninstalled Logitech’s SetPoint software for my mouse from my Windows XP machine. After uninstalling it, I started receiving the following error every time I started Outlook (see image below as well).
The Add-in “Redemption Helper Outlook Extension: (C:\Program Files\Logitech\SetPoint\KEMMAPI.dll) cannot be loaded and has been disabled by Outlook. Please contact the Add-in manufacturer for an update. If no update is available, please uninstall the Add-in.
After searching around the net for a bit, I came across a solution that worked: delete the file named extend.dat from the C:\Documents and Settings\username\Local Settings\Application Data\Microsoft\Outlook folder. Replace username with your username. That solved the problem.












Thanks, your tip worked great!
I’ve been with this problem for MONTHS.
An now … got rid of it after I read the tip.
Awesome, my Outlook wouldn’t even open, you saved the day!
dll errors are such a pain in the a**
Thanks
Thank you.
and another thanks from me – I had this for a long time, IT wouldn’t know how to solve…I had to search for the solution myself, glad you bothered to share it.
Where is that located on a vista mac hine?
Great tip, Thanks
in Vista the extend.dat is at C:\Users\username\AppData\Local\Microsoft\Outlook
