Uninstall
1. After installing the Office 2007 Primary Interop Assemblies as a part of
the setup of a managed code solution, you should not uninstall the
redistributable. Doing so may remove the PIA’s even if another
managed code solution which installed the Office 2007 Primary Interop
Assemblies is installed. Multiple installations of the Office 2007
Primary Interop Assemblies are not possible, therefore, removing the
redistributable will not take into account other managed code solutions
that are using the included PIA’s. Removal of the Office 2007 Primary
Interop Assemblies should be an end user action from Control
Panel/Add Remove Programs.
2. Uninstalling the Office 2007 Primary Interop Assemblies after
uninstalling the .NET framework will leave the PIA’s on the hard disk in
the Global Assembly Cache (GAC).
