[Thibault 0]

 I've just bought the add on A320 family immersion for Prepar3dv3. I bought it on : The Flight Sim store.When i click on direct install, there is an error message : "The target aircraft must be installed for this product to work. Please refer to your product's manuel". How can I install it ?

Thanks

You need to have your Aerosoft Airbus A318/A319 or Aerosoft Airbus A320/A321 installed for A320 Family Immersion to work
