The binary crashes with GetOverlappedResultEx() not found on Win7, had the same Problem on one of my Game machines. Can't install Win11 because there is no TPM2.0, Win 8+10 are dead/almost dead. If you're on older hardware, Linux (Steamdeck etc) might be a good bet. I definitely would hate to have to fork over ~2000€ to buy new hardware to play a old (but good) MMO.
