My computer does not have a disk drive. Can I download RealFlight G4.x?
A downloadable version of RealFlight G4.x is not available. Installation is only supported from an original four CD ROM set for G4 or a single DVD ROM for G4.5. To install RealFlight G4.x on a computer that does not have a disk drive, you can use an external USB DVD ROM drive. The RealFlight G4.x disks are not referenced for daily operation, so you can store the disks once the installation is complete.
This option may be helpful to you: Several users have reported they were able to install RealFlight G4.5 from a USB flash drive (this option is not available for RealFlight G4 due to the multi-disk set). For that to work, you will need to place the disk contents in the root of the flash drive (do not place the disk contents in a folder). You will also need to rename the flash drive with the same name as the installation disk (RFV4_1). If you do try to install RealFlight G4.5 from a USB flash drive, bear in mind this method is not officially supported.
