BillQuick Outlook Add-In gives an installation error:
PIA assemblies not found.
Make sure that Microsoft Outlook is completely closed while installing the Add-In and try again.
If the installation fails again, try downloading the Primary Interop Assemblies (PIA) component from the Microsoft web site and install it on your system.
