After getting some advice on some hardware problems my AOG has stopped opening on the Toughbook I use. I re-downloaded on a different machine and it runs. I moved it to a Flash Drive and it runs from there even on the Toughbook. As soon as I copied the working folder from the Flash Drive to the Toughbook it no longer opens. I can also open the arduino IDE on the Toughbook so some applications open.
If the data in appdata folder is corrupt (if you perhaps set wrong usb ports) AOG sometimes can´t start again.
On my office PC it would be this folder, or just the latest file in this folder.
