Part 1: Configuring Microsoft Edge (Native Support)

Step 1: Enable the ClickOnce Protocol

You need to flip the master switch to allow Edge to process ClickOnce links.

GPO Path: Computer Configuration or User Configuration -> Administrative Templates -> Microsoft Edge

Policy Name: Allow users to open files using the ClickOnce protocol

Setting: Set to Enabled

Registry alternative: [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Edge] -> Create a DWORD named ClickOnceEnabled and set it to 1.

 

Step 2: Suppress the "Open/Save" File Prompts (Crucial for a seamless experience)

Even if ClickOnce is allowed, Edge will still prompt the user to "Keep" or "Open" the download every time. To auto-launch your specific app, whitelist its hosting domain:

GPO Path: ... -> Administrative Templates -> Microsoft Edge

Policy Name: List of file types that should be automatically opened on download

Setting: Set to Enabled, click Show, and add this exact string:

{"file_extension": "application", "domains": ["your-internal-domain.com"]}

Part 2: Configuring Google Chrome (Requires Extension)

Step 1: Force-Install a ClickOnce Extension

You must push a verified ClickOnce helper extension to your Chrome users. A trusted standard is the Meta4 ClickOnce Launcher or similar enterprise tools.

GPO Path: Computer Configuration or User Configuration -> Administrative Templates -> Google -> Google Chrome -> Extensions

Policy Name: Configure the list of force-installed apps and extensions

Setting: Set to Enabled, click Show, and add the extension ID appended with the update URL.

 

Step 2: Whitelist the App Domain in Chrome

To prevent Chrome from blocking the extension's communication with your website:

GPO Path: ... -> Administrative Templates -> Google Chrome

Policy Name: Allow lists of URLs to open external protocols without a prompt

Setting: Set to Enabled, click Show, and input the format scheme to trust your specific domain:

[{"protocol": "clickonce", "allowed_origins": ["https://your-internal-domain.com"]}]
