CRM Integrator will not work correctly if the installation is performed while Vistas "User Account Control" is on.
Solution: > If CRM Integrator did install, remove it from Programs and Features. If Microsoft Primary Interop Assemblies is installed for 2003 or 2007, Un-install that > Turn "User Account Control" OFF from User Settings within Control Panel. > Run updates for Office to ensure that MS Outlook 2003 or 2007 is up to date. > Re-install CRM for Outlook. - Updated: September 15, 2009
