You should be able to see what mode is the application running in.
If you have a 64-bit Windows 7 or Vista installed then all applications in the Windows Task Manager that are NOT running natively (in 64 bit mode) are marked in the Processes tab as *32. So for example, I have firefox.exe *32 listed there, and obviously it means that the firefox is running in a 32 bit mode, therefore it's a 32bit application, but winword.exe isn't, and it doesn't have the "*32" next to its name.
Did I make this clear?
Now, go and check your Task Manager and run both European and US version to see if there are any differences, then let us know.
Thanks

also note Tranfer is still 32 bit does not default to the 64 bit version you have to go into transfer preferences and direct it to the proper location of cnx2 64 bit or files will just be opened in explorer
