The PearPC control panel is used to set up PearPC. It is a nice application, but we now recommend to users the PearPC VirtulBox GUI instead.
Occasionally, the PearPC Control Panel will return a “Runtime Error 76” and refuse to save or import any config files. If this happens, you must uninstall the control panel, delete the *.ini files remaining in the program directory (they are not removed by the uninstaller) and reinstall the control panel.
