Telling if Visio / Visio Interop are installed?

Hi!

I have a C# application that is hosting a Visio ActiveX control.
In the installer of the application, I want to check if Visio AND Visio
interop are installed, and block installation if these prerequisites
are not met.

Could you kindly advise me of a way to tell if the proper Visio & Visio
Interop are installed?

Thanks,
Gil

I am affread it is not right answer, but if CreateObject("Visio.Application")
returns error, Viso may not be installed.
