I recently upgraded to 8.0.3 and tried to install the VAC on my machine and am running into this issue again. Originally, it worked fine to install the Oulook Add-In first and then install the VAC. Now, I have uninstalled the 8.0.1 add-in, uninstalled the 8.0.1 VAC, rebooted, installed the 8.0.3 add-ins, run Outlook to verify the install was complete and working, reinstalled the 8.0.3 VAC and rebooted. After reboot the add-ins act as if they need to complete the install again and then throw the error message. Even so, if I click OK a couple times the add-ins are installed and seem to work. However, if I run Tech Info I get an error on the http connection:
