I am trying to install lookout (outlook search plugin) on Office 2007 and windows 7. I already have it working on office 2007 but on XP. WHen i try doing the same install on Windows 7 I get the error:

I can't write some of my program files because they are in use. Please stop Outlook and Retry and then i can continue

I get this error even if outlook is not running.

Has anyone gotten lookout outlook plugin to work on Windows 7 and Outlook 2007
