I noticed that the installation is installing both modules for 32-bits and 64-bits. My question is why I see:
these files look like 64 bits files...
and vice versa
it seems the 32-bits files are in the 64-bits folder and vice-versa...
The files are in the correct location. On a 64-bit system, system32 is the 64-bit directory and SysWOW64 is the 32-bit directory. WOW64 = Windows 32-bit on Windows 64-bit. See WoW64 - Wikipedia, the free encyclopedia and Running 32-bit Applications (Windows) for more information.
