adobe reader 32bits get auto upgraded to adobe pro x64

hi we are running a lot of terminal windows servers and i have set all the keys.

but adobe reader keeps on getting upgraded from adobe reader 32 bits to a x64 adobe pro.

am i missing something? is there anyway to stop this behavior?

already set these keys:
