It looks like the FPSE could only be installed with the user account "Administrator". Even if you use another account in adminsitrators group, the installation could fail. In addition, have you tired to run the setup file with administrator?

Please ensure your current user identity have enough permission to access IIS configuration.
In addition, it is recommended to consult the FPSE issue from their vendor.
