VSTO install package-How to check for prerequisites and skip them
 

Hello all,

I created Setup Package for My Excel add-in projetc according to the article
"Deploying Visual Studio 2005 Tools for Office Second Edition Solutions Using
Windows Installer"

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

I don't want to run msi file ,I want to run setup file

Thanks a lot
