Several people have told me they are getting the following error message when trying to run the simulator:

This error occurs because GTK was not installed properly. When installing the simulator make sure you install GTK as well. The simulator installer will ask you if you want to install GTK (see screen 7 below). Click OK at that time to install GTK. GTK provides the graphics libraries needed by the simulator.
If you have already installed the simualtor, then:
1. Uninstall both PSATSim and GTK (from the control panel->add remove
programs window).
2. Reboot your computer.
3. Follow the steps below to install the simulator.
