On several places in this form I read:"I try to open RadarContact for MS Flight SImulator and receive an error saying "Component MSINET.OCX or one of its dependencies not correctly registerd: a file is mission or invalid."It seem that this problem is due to Windows Vista.Everytime the administrator point to solutions, but I never read that the problem is over.I tried everthing, but my radar contact in my vista don't start. Only always that same message.Ik would like to know if there is somebody with a working Radar Contact in Vista. Otherwise it seems a waste of money to buy it for Vista owners.Greets Rick.
