Visual Studio 2010 redistributable

Hi,

I developed software using Visual Studio 2010 C++.  I have VS 2010 SP1 installed.

When I install my software on some machines, depending on what is already installed on the machine, I get a warning that a newer version of the Visual Studio redistributable already exists.

Does this message concern the different versions of VS, like 2010 and 1012, or different versions of the VS 2010 redistributable?

How many versions of vcredist_x86 (aka VS 2010 redistributable) exist for Visual Studio 2010?  And how / where do I get them?

Thanks.
