How to determine whether dotnet and VSTORuntime is installed in WIX Bootstrapper

Question

i made a setup file of my Add-Ins project using wix. it has some dependencies like dotNet and VSTO Runtime. so I used Wix bootstrapper to confirm that dependencies must be installed before installing the product it works too. But i need conditional installation of dependencies like if dotNet and VSTO runtime is installed then don't look for install these items. i tried the registry searches too but didn't get success, here is my bootstrapper code tell me where i need to modify my code.

Another issue i have is, i attached the mylicense.rft which has some dummy contents. but setup doesn't show the license content during installation process, look at the attached snapshot

Answer 1

The issue was I forget to use value attribute which causes this problem. This was problem with rtf file, after changing the file it worked as expected. Here is the working version of code.

Working version is here
