How to determine if VSTO 2010 Runtime is Installed?

Question

It was easy to check if VSTO 2005 SE was installed by just calling MsiGetProductInfo() with the product code {388E4B09-3E71-4649-8921-F44A3A2954A7}, as listed in MSDN.

What is the product code for the VSTO 2010/4.0 runtime? Or is there a better way to determine if it's already installed? This is for our installation process.

Thanks!

Also, I am trying to figure out the same for Windows Imaging Component.

Answer 1

The easiest way is to check the registry.

HKLM\Microsoft\vsto runtime setup\v4\Install

HKLM\Microsoft\vsto runtime setup\v4R\VSTORFeature_CLR40 (this is for the 4.0 Office extensions)
