Install Silverlight pseudo winfrom Using InstallShield

As we all know, the Silverlight OOB mode can be directly installed right-click in the browser,
Here I will introduce how to use SilverlightProgramCreate an independent EXE installer.
Ideas:
1. Install xap through command line
2. After installation, uninstall the xap that comes with OOB In the delete control panel.
3. InstallShield installer uninstall and also uninstall the Silverlight Program

Prerequisites:
