STK (Systems Tool Kit) by Ansys/AGI crashes on launch - Parallels 26 / MacBook Pro M5 / Windows 11 ARM
Hi everyone,
I am trying to run AGI STK (Systems Tool Kit) inside a Windows 11 virtual machine on Parallels Desktop 26, on a MacBook Pro with Apple M5 chip. STK crashes silently every time a new scenario is created, before any user interaction is possible.
Here is my setup:
∙ Mac: MacBook Pro, Apple M5
∙ Parallels Desktop: version 26 (latest)
∙ Guest OS: Windows 11 ARM (Home and Pro, both tested)
∙ STK versions tested: 12.9.1, 12.10.1 -- all crash identically
The Windows Event Viewer shows the following error on every crash:
∙ Faulting application: AgUiApplication.exe
∙ Faulting module: AgGx3dScene.dll
∙ Exception code: 0xc0000005 (Access Violation)
This is clearly a rendering/GPU issue. STK uses legacy OpenGL for its 3D scene engine.
Workarounds already attempted without success:
∙ Enabled "Use software rendering" in STK Preferences > General > Graphics
∙ Disabled GPU Accelerated Analysis
∙ Set AgUiApplication.exe to "Power saving" in Windows graphics settings
∙ Launched STK with -softwareRendering flag (not recognized in STK 12.10)

Anyone any help? Thank you in advance
