You do not have to have previous versions of realflight installed to install a upgrade version. All you need is the interlink serial number. All of the RealFlight software discs are the same for each version, just one comes without the interlink or interface device. If 7.5 is the only version that you want, you can just install the 7.5 upgrade without having to install 5.5 and 6....
