TopoFlight can be run either with a software or a hardware license. Please check "Registration" for further information.

For testing TopoFlight download TopoFlight7_SoftwareLicense (TopoFlightSetup.zip contains the software, TFVersion.ver some information about the current version). Extract all files and install the software. Send the machine code to info@topoflight.com to get a demo license and copy the file you get in response (TF7License.ldf) in the same directory where topoflight.exe is stored. A demo license allows the usage of TopoFlight without any restrictions for 10 days.

When purchasing TopoFlight decide which registration option you'd like to choose and either download TopoFlight7_SoftwareLicense or TopoFlight7_HardlockLicense from the links below (TopoFlightSetup.zip contains the software, TFVersion.ver some information about the current version).
If there already is a software license installation on the computer (which for example was used for testing with a demo license) and you want to go on with software registration just replace the license file (after purchasing the software a new TF7License.ldf is provided).
If there is already a software license installation on the computer and you want to switch to hardlock registration deinstall the software and install TopoFlightHardlock. The software will run after plugging the provided USB Hardlock.
