I am a long time owner and user of Falcon 4 and do have several copies of the install CD’s, “Legitimate” copies. I am running windows 10. My problem is installation for the new BMS upgrade 4.33. I cannot get Falcon 4 to install, it just hangs in task manager. I have played with all possible compatibility settings, and have checked to run in administration mode. I have tried the lower graphic settings as well. and to no avail. I tried all the known possibilities through my years of dealing with stubborn installations and now I have no choice but to ask for help if someone may have an answer to what maybe an antiquated software to be installed on a newer OS.
