Hello, I have just bought a new computer (PC) running Windows 10, and have downloaded and installed PixInsight and 24 updates, after copying my licence file to the new machine. The installation went OK and PixInsight opened in the normal way, but when I closed the programme the error message "Error writing settings data (bool)" was displayed. The first time it was displayed it was simply labelled as an Error. The next time this happened it was labelled a Fatal Error. My browser is Microsoft Edge. Roy Axelsen
