AirKey control panel is not displayed

Problem:
The contents of AirKey control panel is not displayed when the panel is opened. However, no error occurs.

Cause:
The interface of Axidian AirKey Enterprise control panel is implemented using Qt Quick 2 dynamic library, which requires OpenGL and hardware graphics acceleration. These might not be supported in some PC and OS configurations. 

Solution:
To use Qt Quick 2 in configurations with no OpenGL support, you need to resort to Qt Quick 2D Renderer.
To enable Qt Quick 2D Renderer, add QMLSCENE_DEVICE variable to OS environment parameters and set this variable to softwarecontext value.
The QMLSCENE_DEVICE variable can be propagated to all computers of a domain via group policies or manually by editing the registry (see the example below or use the attached QMLSCENE_DEVICE.reg file):

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Session Manager\Environment]
"QMLSCENE_DEVICE"="softwarecontext"

The workstation has to be restarted after making changes.
