PowerLine Transmission tower in Airsim

[MostafaAhmed95]

My goal is to create a simple environment which contain a power line transmission tower so I downloaded the Landscape Mountain environment, extract it, open UE4editor then choose open project but I got the following error

Project files could not be generated. Log output:
