ClickOnce application when run from start menu gets the URL it was originally downloaded from

Our users run our ClickOnce WPF application from the start menu / desktop shortcut. When the application starts each time we need to get the URL it was originally downloaded from. I tried using the ActivationUri, but this only works when it was run directly from the website setup.exe rather than the desktop / start menu shortcut:

string activationUri = "???";
try
{
    if (System.Deployment.Application.ApplicationDeployment.CurrentDeployment == null)
    {
        activationUri = "currentDeployment is null";
    }
    else if (System.Deployment.Application.ApplicationDeployment.CurrentDeployment.ActivationUri == null)
    {
        activationUri = "deployment not null but uri is";
    }
    else if (System.Deployment.Application.ApplicationDeployment.CurrentDeployment.ActivationUri != null)
    {
        activationUri =
            System.Deployment.Application.ApplicationDeployment.CurrentDeployment.ActivationUri.AbsoluteUri;
    }
}
catch (Exception ex)
{
    activationUri = ex.Message;
    //Error getting the URL so put question mark
}

MessageBox.Show(activationUri);

When run from the setup (from a website) I would get the URL, and every other time I would get "deployment not null but URI is".

ApplicationDeployment.CurrentDeployment.ActivationUri

is not null if you activate the "Allow URL Parameters to be passed to the application" checkbox in the Publish Manifest options.

Otherwise use ApplicationDeployment.CurrentDeployment.UpdateLocation!

I think all you can do is save the URI somewhere when the application downloads and runs the first time and then reference this value when the application runs offline.

Try ApplicationDeployment.UpdateLocation property. Unless you have configured a different update URL in the Project Properties -> Publish -> Updates -> Update Location in Visual Studio, it should return you the original deployment URL.
