The ClickOnce installer will download all DEPLOY files automatically strip the deploy extension and install the application. Accept any security prompts to complete the installation process. 2️⃣ Troubleshooting Installation If ClickOnce installation fails open Event Viewer and check Application logs for deployment errors. Clear the ClickOnce application cache by running rundll32 dfshim CleanOnlineAppCache in the Run dialog. Retry the installation from the original deployment URL. 3️⃣ Manual File Extraction If you need to inspect DEPLOY files manually rename them by removing the .deploy extension to reveal the original file type. A file named app.exe.deploy becomes app.exe after renaming. This allows inspection of the application binaries outside the ClickOnce deployment framework. ________________ Timestamps: 00:00 - Open DEPLOY File (Quick Start) 00:28 - The DEPLOY Extension 00:44 - DEPLOY File Format Composition 01:02 - How Do I Open a DEPLOY? 01:19 - How to Load DEPLOY 01:47 - DEPLOY Solutions 02:53 - Third-Party Universal Viewers
