How do I check that a browser has ClickOnce enabled?

Question

My software, [https://jazzsoftware.co.nz/], is written with VB.Net, and is delivered with ClickOnce. I've tried to make it very clear in the relevant web pages and the setup instructions [https://www.jazzsoftware.co.nz/Docs/JazzSetup.htm] that users wanting to download MUST use a browser enabled for ClickOnce, and Setup includes instructions on how to enable this in Edge. Yet it is very common for users to require several download attempts before they succeed (or give up?)

How can I check that the user's browser has ClickOnce enabled? If I could do this as the first step when they clicked [Download] I could provide a better experience and hopefully a higher success rate.

Thank you, Robert

Hi @Robert Barnes,

For all Windows users, ClickOnce is supported out of the box.

To check whether ClickOnce is enabled, go to edge://flags/#edge-click-once and select Enable from the drop-down list. You must restart the browser.
