Wix bundle custom UI: Repair failed if the the original source setup is deleted

Executing Modify/Repair from "Program & Features" fail if the original source setup is not found.

Created a bootstrapper with custom UI that has Repair feature. The Repair button is enabled when setup is already installed, which executes following code.

    private void RepairExecute()
    {
        Bootstrapper.Engine.Plan(LaunchAction.Repair);
    }

After installing delete the setup file. Go to "Program & Features" and modify the setup. Press Repair button and it fail. Following are log entries
