Can there be problems with WinCC OA installation and Matrox cards ?

Yes.
In rare cases installation of WinCC OA 3.17+ is not possible due to a conflict with Qt and the Matrox driver.

Recommendation:

  • Install the newest Matrox driver.
  • Set the environment variable QT_OPENGL and try one of the following values: 
    • software
    • angle
    • desktop
