For your convenience, there are multiple ways to upgrade your RealFlight G4 to G4.5. Please note that the upgrade file size is large and may take a while to download. The different methods to obtain the upgrade include:
RealFlight Launcher
Clicking the RealFlight G4 icon on your computer opens the RealFlight Launcher. Instead of clicking Run RealFlight, click the Additional Options button. Then click Registration/Updates button. A new window will appear that will allow you to register and update your RealFlight simulator. Simply click Update to Latest Version and follow the on-screen instructions.
Download the Upgrade File
If you prefer, you can download a self-installing upgrade file from here: RealFlight4_50_021.exe - 987 MB
Download this file and run it on the computer which RealFlight G4 is installed.
Burn your own Upgrade DVD
If you prefer to download the upgrade on a different computer than the one RealFlight G4 is installed on, or if you wish to share the upgrade with other G4 owners, you may want to choose this option. If you have a DVD burner, download the following disc image: RFV4UP_4_50_021.iso - 988 MB
Burn this to a DVD using your DVD writing software. Once this DVD is created, insert it into the computer that has RealFlight G4. This disc will autostart and begin the installation.
