Perfect advise by you and others!
- Yadd/Yand should not be installed anywhere UNDER .../program files/ unless you have full admin rights
to that directory. The installer will give you the option to install in c:/whatever you wish. please read the user manual. During the install, don't click OK OK OK without reading the options.
- By default, Yadd will make a shortcut to yadd.exe in the directory it was installed in.
You cannot start Yadd multiple times from that same shortcut. The screenshot you posted clearly proves that is what has happened.
