ClickOnce Application won't launch unless host has (or had) Visual Studio Installed RRS feed

  • User-405644719 posted

    We have a basic Windows Forms application, which acts as a shell around a CefSharp browser and is distributed to our clients via ClickOnce deployment.
    Generally we haven't had many issues with people installing this application, as most of our clients have been upgrading from a previous .Net desktop application. However some of our newer clients have been purchasing brand new computers with a clean install of Windows 10, and in those cases the application fails to start unless we install a copy of Visual Studio, and then remove it to save disk space.

    The error we see is this:
    Framework Version: v4.0.30319
    Description: The process was terminated due to an unhandled exception.
    Exception Info: System.IO.FileNotFoundException
       at App.Client.Program.Main()

    Followed by a standard appcrash report:
    Faulting application name: App POS.exe, version: 1.0.0.0, time stamp: 0x5e87294b
    Faulting module name: KERNELBASE.dll, version: 10.0.18362.418, time stamp: 0x2b181c2c
    Exception code: 0xe0434352
    Fault offset: 0x00113572
    Faulting process id: 0x17d4
    Faulting application start time: 0x01d6280dfdaf68fd
    Faulting application path: C:\...\App POS.exe
    Faulting module path: C:\Windows\System32\KERNELBASE.dll

    It seems like the clickonce launcher is not pointing to the correct application packages location, since it can't even find the entry point in Program.Main(). 
    The files and manifests all install correctly into the AppData directory, identical to what we see on other machines. No changes have to be made after installing VS. The application just runs where it had failed before.

    Is there a known way around this so we do not have to continue to download a very large and unnecessary IDE onto our clients' business machines? Does clickonce have some hidden .net/sdk dependencies that we're missing?

    Thanks!
