  My Ansys EM suite does not start at all. I cannot get it to open by using the icon or by loading a project. Any help would be great. Thanks!n

  A recent Windows update, Microsoft update KB4571756, results in one of the Windows functions (DescribePixelFormat) crashing on startup. n nFor versions 2018.0 and newer, please try setting the environment variable ANSYS_EM_DONOT_PRELOAD_3DDRIVER_DLL=1 to get around the problem.n nFor guidance on creating an Environment Variable please refer to this link. You need to create a NEW Variable.nhttps://www.onmsft.com/how-to/how-to-set-an-environment-variable-in-windows-10n nNew Variable Name: ANSYS_EM_DONOT_PRELOAD_3DDRIVER_DLLnNew Variable Value: 1nn
