After installation, Outlook greeted me with the following error:
Sorry!! It looks like another Outlook Plugin has installed an unofficial version of the Outlook libraries which breaks Lookout. Lookout will not be able to load. For more information, see this link: http://www.lookoutsoft.com/forums/topic.asp?topic_id=10
Unfortunately, the aforementioned link doesn’t offer many leads on why the problem occurs, nor how to work around it. I have a few COM add-ins loaded, including SpamBayes, some thingy MapPoint installed, and one I wrote myself in C# to redirect email to a web account. I was guessing my software was causing the problem.
I think the problem occurs because Lookout uses the primary interop assembly for Office XP, while the add-in I wrote uses the PIA for Office 2003. I opened my project in the IDE to see if I could get the two working together when all hell broke loose.
Each time I tried to do anything with the add-in project I wrote, Visual Studio crashed and sent an error report. After the error reporting finished, a dialog would appear to tell me updates are available which might fix my problem, and I was sent to the Office updates page. After installing updates, I could not even open Visual Studio without a crash, so I rebooted.
After rebooting, everything appeared to be back to normal, and Lookout started to work once I disabled my C# add-in. I decided this wasn’t a battle I wanted to fight, and scrubbed out every reference to my component from the registry. My add-in isn’t highly useful, but Lookout is fantastic.
