Hi everyone!

I'm sorry if this is a really simple question.
Please can someone on here tell me in simple terms what Microsoft C++ is?
See I've got a friend of mine who wants to use the Vocalizer voices with NVDA downloaded from a website I know about, but he doesn't have Microsoft C++ installed.
And I'm not sure how to explain what they are because I don't know properly myself.

I've tried a Google search for this question, getting the answer Integrated development environment.
But I don't understand what this means.

Thanks I look forward to any replies.
