Problem

A CHARON virtual machine can be started using the launcher but fails with segmentation violation when started as a service

Related versions: CHARON-VAX V4.7¹ running on Windows 7 and Windows 2008 R2²

¹: other versions could be affected

²: case not reproduced on other Windows versions

After an upgrade or a patch installation, the workaround must be applied again

Open the System Properties, Advanced system settings or run "systempropertiesadvanced" from the Windows Run command (Windows Key + R ), click on Performance Settings.
Select the "Data Execution Prevention" tab then:
- either verify "Turn on DEP for all programs and services except those I select" is checked, find the emulator in the list, remove it and add it again (no reboot necessary).
- or check the "Turn on DEP for essential Windows programs and services only" box (reboot mandatory).
  This is the recommended solution to avoid applying the workaround after an upgrade or a patch installation.
Start the CHARON service
If the service still fails to start, please contact support

Emulator exe file is in this case located in "C:\Program Files (x86)\CHARON\Build_17101\x86" folder
