Question

I am developing an application. I’m using ClickOnce of Microsoft to install my application on user’s computer. Now I want to check for prerequsites if they are installed and ready to use. So how can I do that?

Answer 1

Refer to the documentation on How to: Install Prerequisites with a ClickOnce Application, in particular the quote:

When publishing a ClickOnce application, you can choose a set of prerequisite components to be packaged along with your application. At installation time, a check will be performed for each prerequisite to determine if it already exists; if not it will be installed prior to installing the ClickOnce application.
