can anyone help me ? im just wondering do you have to download all files ? or just the latest one ? why isnt the game downloading thannks

You only need to download one file.

Choose the one for your operating system. Choose the latest build.

When the zip file has downloaded completely, unzip it to a folder of your choice.

It will look a bit different depending on the operating system -

On Windows, it should be a FPVFreerider.exe file and a FPVFreerider_Data folder.

Double-click the exe file to run the simulator.
