Outlook 2007 with Nav 5SP1 - Outlook toolbar doesn't respond

nav_nav

Hi,

I am trying to install the Outlook add-in for NAV 5SP1. It does install correctly, I manage to get the toolbar displayed in Outlook.
When I click settings on my laptop, nothing happens. On another device the settings window does pop up.
I have to be honest and say that multiple instances of NAV had been installed on that laptop. I hope I did uninstall everything, but perhaps I missed something.

Some more information : Outlook, Trust Center, Add-Ins, Flag Apply Macro Security Setting to installed add-ins, select COM Add-Ins and hit Go. When I click on Micorosoft Dynamics NAV Synchronisation Add-In (which is deselected) I do notice that below it says : 'A runtime error occured during the loading of the COM Add-In'.

Any idea ?

Thanks.
