Boxstarter error in Edge

[johnnyramrod]

Microsoft docs tell me I have to use Edge to have the installer work (see here: https://docs.microsoft.com/en-us/learn/modules/introduction-to-windows10-dev/2-installing-tools-automatically).

However, when trying to launch the Full App install, it fails. Error Summary in log says:

ERROR SUMMARY Below is a summary of the errors, details of these errors are listed later in the log.

• Activation of C:\Users\xxxx\Downloads\Boxstarter.WebLaunch.application resulted in exception. Following failure messages were detected:
  • Deployment and application do not have matching security zones.

Don't know what this actually means or how to resolve it. I'm not getting asked to elevate permissions etc. I am logged in with an admin account.

Same error message for me. I never even heard of .application files and I have no idea what is actually happening.

In case it helps, here is the stack

A .application file is a launcher for a ClickOnce application. The browser downloads it like a normal file; but then if the browser recognizes it (pretty much only IE and Edge, since it's a Microsoft technology), then it will follow the instructions within to download the rest of the application files from the same host, and execute them.

However it seems the feature is disabled by default in the current version of Edge. I got it to work by opening Edge, navigating to edge://flags/#edge-click-once and setting it to Enabled, then closing and re-launching Edge as Administrator (just in case) and navigating back to the Boxstarter URL.

Hope that helps.
