I created Setup project for my Excel add-in project according to the article:
Deploying a Visual Studio Tools for the Office System 3.0 Solution for the 2007 Microsoft Office System Using Windows Installer
http://msdn.microsoft.com/en-us/library/cc563937(office.12).aspx
I add prerequisites such as 2007 Interop assemblies(Office2007PIA) and when I run my setup file it does install it. But the problem is : That my setup ALWAYS installs it even if my computer already has Office2007PIA.
How can I configure my setup project that it will first check if Office2007PIA is installed and continue the installation of my project without installing Office2007PIA?
Thanks!
