How to find exe in C++ through registry?

Question

C++ / C#

It is necessary through C ++ (preferably winapi) or other libraries (not dll and not lib, such as boost, etc.) to find the path to the exe program. For example steam or skype.

Answer 1

And where did you get the idea that there will be a path to skype or steam in the registry?
You can search your registry and see if it's there now.
But do not forget that these are proprietary products, and no one guarantees in which branch of the registry in which version of Skype there will or will not be such information.
