I have a VSTO add-in that I want to install without promting the user. This add-in is not installed in Program Files folder. For now I have a solution described in this article: https://msdn.microsoft.com/en-us/library/bb398239.aspx It is easy to use and works perfectly. The problem is, this function was removed from VSTO runtime in version 10.0 (it worked in VSTO runtime 9.0).
Time passed, and now most of my users use Windows 10 and don't have .NET Framework 3.5 preinstalled. I could force them to install it, but I thought that mabe moving forward would be a better solution. So, I would like to add an add-in to inclusion list but without using the function I mentioned above. I guess the only way is to put proper registry keys in place by myself.
So the question is, which registry keys should I add or change to make it work?
