As long as that relates to the MobiLink server binaries, that's expected behaviour as of v12.0.1:
To cite from the changes page:
> 32-bit MobiLink server is no longer supported on 64-bit operating systems On 64-bit operating systems, the MobiLink server is only installed as a 64-bit application and must be run as a 64-bit application. Any 32-bit versions of the MobiLink server that might remain on your system from previous version 12 installations cannot be run on a 64-bit system.
