How to determine if Visual C ++ 2017 Redistributable will be installed

Question

When Microsoft changes the registry entry template in its latest versions, how can I determine if Visual C ++ 2017 Redistributable is installed on my computer?

My goal is to install VC ++ 2015Redist since the software is written using VS2015. If I can successfully detect VC ++ 2017Redist on the machine, then I will skip the installation of VC ++ 2015Redist

Answer 3

You are solving the wrong problem. You are trying to install an outdated, redistributable that is only suitable for VS2015 (Toolset v140). Instead, install the current redistributable VS2017 (Toolset v141). It is backward compatible with VS2015.
