I installed xobni plus on my computer, but can't seem to make it work. So I'm trying to uninstall the add-in to re-install to make it work.

When i go to the trust center and click on the com add-ins to remove it, it tells me i have to be an adminstrator to remove it. I am an administrator.

I'm using outlook 2007 in Windows 7 Ultimate.

Thanks for your input.

    Can you not uninstall Xobni through Start menu -> Control panel -> Programs and features ?

    I would open the Windows Task Manager, go to the "processes" tab, select "show processes from all users", and make sure all Outlook.exe and "XobniService" processes are gone . Then, go to control panel, add/remove programs (or Programs and Features, if you are using Vista), scroll down to Xobni, click remove, and click remove from the repair console that appears.

    Try Outlook again to see if it is gone now. IF it still shows up, close Outlook and then make sure no Outlook.exe processes are showing up in the task manager again, then, delete the following directories:

    C:\Program Files\Xobni (or C:\Program Files (x86)\Xobni)

    XP: C:\Documents and Settings\Username\Local Settings\Application Data\Xobni\OutlookProfileName

    Vista: C:\Users\[Your Name]\AppData\Local\Xobni\[Outlook Profile Name]

    You might need to turn on 'Show hidden files and folders' in the Control Panel > Folder Options > View tab, in order to see the Xobni data directory listed above.

    If you start Outlook again now, Xobni shouldn't show up. Post an update here on how this goes though and if Xobni continues to show up in Outlook for you, maybe I can suggest other things to try.

    FYI: Assuming this does work to remove Xobni from Outlook, it may still show up in control panel, add/remove programs. That isn't a "problem" but if this bothers you, you can go to it again add/remove programs and click remove. You'll get an error since it's gone now. Windows may then ask if you want to remove it from the list. If you can't remove it from the list, there are other things you can try to do this. If you have that problem, just post an update to this post and I'll try to suggest a solution to that.

    If you want it back then I suggest  reinstalling .NET, I'd recommend V3.5, which you can download from Microsoft
    from here :

    I tried all of the solutions in this thread to get Xobni uninstalled, reinstalled to try to make it work and then settled on this to unload it completely. (I knew this solution, but it was the one I had to resort to...)
