My computer does not have a disk drive. Can I download RealFlight 8.x?
A downloadable version of RealFlight 8.x is available for purchase from Tower Hobbies and from the Steam Distribution Platform.
To install the DVD version of RealFlight 8.x on a computer that does not have a disk drive, you can use an external USB DVD ROM drive. You will not need the RealFlight 8.x disk for daily operation, so you can store the disk once the installation is complete.
This option may be helpful to you: Several users have reported they were able to install RealFlight 8.x from a USB flash drive. 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 (RFV8_1). If you do try to install RealFlight 8.x from a USB flash drive, bear in mind this method is not officially supported.
