qtdemo.exe runs with administrator privileges when started from installer

The installer of Qt allows to start qtdemo.exe directly from the installer. If I do this, it runs with elevated privileges, e. g. I can access other users' home directories using Text Edit demo.

Instead of this, the qtdemo should always run with the normal user privileges as if I had started it from the Start menu.

I guess Qt Assistant runs with elevated privileges, too.
