Microsoft C++ Always Installed

[ClintBeastWood]

This is just a quick question. Why do programs that need Microsoft C++ not just check if I already have it on my system? It just installs it. If they stacked I would have hundreds. Is it just how it runs? Or is the program not permitted to check those files?
Some one enlighten me please.

The authors of the programs were probably too lazy to write their code to check for its existence. Either that or there is not a good way to verify that C++ is already installed.

What you mean bu "installing C++"? Most of these programs install run-time libraries only, not the whole development system (which would be breach of copyright anyway).
