Starting AX2012 with a specific configuration file

I was just providing access to an ax environment through Citrix. The goal was to provide an .axc configuration file that directs the Client to a specific AOS. So i was looking for a startup command that could help. And tried to use ax32.exe -regConfig. But it's even easier, you just need to place the config file behind the ax32.exe. Thats it :)

“C:\Program Files (x86)\Microsoft Dynamics Ax\60\Client\Bin\Ax32.exe” “X:\DynamicsAXConfigurations\AX2012R2_TEST.axc”
