Why am I getting a "protection error" when I install/run on Windows on ARM?

Since the release of Windows on ARM with Windows 10 it has been possible to use Windows with processors other than the usual x86/x64 types and various Laptops have been released using e.g. Snapdragon (ARM) CPUs. Windows on ARM implements emulation to support x86/x64 software on ARM, but this causes incompatibility issues in some cases - such as the GS-911 Diagnostics PC App and its installer.

This is also applicable to MacOS users running Windows 10+ within Parallels on an ARM processor, like the Apple M1.

The Problem

When launching the GS-911 Diagnostics PC App or its installer on a Windows on ARM PC or VM you might see a "Internal protection error, please contact support" message and the software will freeze/crash.

The Fix

To make the software work you need to enable "Safe emulation" in the file properties.
Right-click on the following files and select Properties->Compatibility->Change emulation settings->Safe emulation

  • GS-911Diagnostics-vYYMM.V.exe
  • GS-911.exe in the installation directory after install
