My computer does not have a disk drive. Can I download RealFlight G3.x?

A downloadable version of RealFlight G3.x is not available. Installation is only supported from an original, two CD ROM set for RealFlight G3 or three CD ROM set for RealFlight G3.5. To install RealFlight G3.x on a computer that does not have a disk drive, you can use an external USB CD or DVD ROM drive. The RealFlight G3.x disks are not referenced for daily operation, so you can store the disks once the installation is complete.
