I will answer you in English as you are on the English forum, and in order to help other who may have the same question.
Your 64-bit PC can run both 32-bit and 64-bit applications, so it is normal to have both versions of Microsoft Visual C++.
I advise you to not uninstall the 32-bit version of Microsoft Visual C++, even if you have a 64-bit PC, because some 32-bit applications need the 32-bit version to work properly.
