WOU will only update already existing C++ versions to the most recent version, regardless of their architecture version.
If you have old versions of say C++2008 installed in both x86 and x64, WOU will update both versions. If you only have c++2010 x86 installed WOU will only update this version but will not install the C++2010 x64 version.

I want to say that all did not install before

So what do you want with the c++ runtimes
If a software needs them they will be delivered (bundeled) with that software and installed during the setup of the software.
Unfortunatelly these bundeled runtimes are not actual (most recent) in most cases.
The installation part of WSUSOU (UpdateInstaller) will regognize an installed runtime (which ever it is) and then update it (if it´s NOT the most recent).
