No, leave them alone.
Different versions are required for different applications that you use, and the 32-bit versions (x86) of Visual C++ are required for 32-bit versions of applications you use (Visual C++ 64-bit is no good for 32-bit applications).
That's why all existing versions of Visual C++ are left intact whenever you install a different version.
Ok, thanks for the tip
