If your ClickOnce application is not starting on Windows 1803 (or later versions), there could be a few reasons for this behavior. Here are some troubleshooting steps to identify and resolve the issue:

  1. Check Application Logs:
    Check the Windows Event Viewer for any application logs related to your ClickOnce application. Look for error messages or any relevant information that might indicate the cause of the issue.

  2. Check ClickOnce Trust Settings:
    Ensure that the ClickOnce application is trusted on the client machine. In some cases, the application might not run if it is not trusted. You can check the ClickOnce trust settings by going to "Control Panel" > "Internet Options" > "Security" > "Trusted Sites" > "Sites." Add the URL of the ClickOnce application to the trusted sites list.

  3. Verify .NET Framework Version:
    Make sure that the client machine has the required version of the .NET Framework installed to run the ClickOnce application. Ensure that the application is targeting the correct version of the .NET Framework.

  4. Check Windows Firewall and Antivirus:
    Verify that the Windows Firewall or any antivirus software is not blocking the ClickOnce application from running. Temporarily disable the firewall or antivirus software and see if the application starts.

  5. Update the ClickOnce Application:
    Check if there are any updates or newer versions of the ClickOnce application available. Try to update the application and see if the issue is resolved.

  6. Reinstall .NET Framework:
    If none of the above steps work, try reinstalling the .NET Framework on the client machine. Sometimes, a corrupted or incomplete installation of the .NET Framework can cause issues with ClickOnce applications.

  7. Check Dependencies and Prerequisites:
    Ensure that the client machine meets all the prerequisites and dependencies required by the ClickOnce application. This includes any specific software or libraries that the application relies on.

  8. Contact Application Vendor:
    If the ClickOnce application is developed by a third-party vendor, consider reaching out to them for support. They might have specific troubleshooting steps or updates available to address compatibility issues.

Keep in mind that the behavior of ClickOnce applications might vary depending on the specific environment and configuration. It's essential to identify the root cause of the issue to find an appropriate solution. If you are still facing problems, consider seeking assistance from your organization's IT support or a technical expert.
