Installation Failed: The Process was Terminated due to an Unhandled Exception

When trying to run the ComponentOne Control Panel web installer, the following error occurs: “The process was terminated due to an unhandled exception”

To troubleshoot the issue, you can try the following:

1. If behind a firewall, try to whitelist the following urls.

   1. https://s1stage.componentone.com

   2. https://gcpkg.blob.core.windows.net

   3. https://developer.mescius.com

   4. https://prod-cdn.grapecity.com

   5. https://www.grapecity.com

2. If you have Dynamic Code Security turned on, disable it temporarily to run the installer. The easiest method is often using the graphical WDAC (Windows Defender Application Control) Wizard:

   • Open your existing WDAC policy XML file within the Wizard.

   • Navigate to the Policy Rules section.

   • Find the option for Dynamic Code Security (Option 19).

   • Ensure this option is unchecked/disabled. In the policy XML file, this option is present if it's enabled and absent if it's disabled (which is the default, less secure, setting).

   • Export the updated policy, convert it to its binary format (.p7b or .bin), and deploy it using your chosen method (e.g., Intune, Group Policy).
