Thx, But I think I have screwed up it even more.

By mistake I removed the Salesforce Add-in to Outlook, now I go to OUtlook--> Tools-> Trust Center-> Add-ins

and try to enable the SF Add-i, I get error that since Sforce was install for all users...this option can only be Connected or Disconnected by an Administrator, funny part is I (user)  am the administrator  on the Vista machine..

ANyone seen this..

I have completely uninstalled and reinstalled Outlook SF integrator plugin but still same error.
