Visual Cpp Redistributable

Microsoft Visual C++ Redistributables. These are required so that the executables of some programs will run, because they were compiled by their author using Microsoft Visual Studio (and a particular version of Visual Studio at that) and require Visual Studio's 'runtime' for C++ in order to run. Usually such runtimes are bundled with the software that requires them, but not always.

There seem to be different versions of vcredist_x86.exe, perhaps language dependent, so there are different MSI removal strings.
