Hi Joris,
My guess is that Xpress is picking up an OEM license. In this case, the Python interface cannot read the control names until Xpress has been initialized by calling the xp.license() function.

Note that Xpress might also look for a license file at /opt/xpressmp/bin/xpauth.xpr, so I suggest you check this too.
Regards,
Chris
