dt connect 2 pcs after network and folders shared. u need to download the zip file in both machines? if yes in one install DATAPROVIDER and in the other DISPLAY UNIT,

 

if yes the validation key,will work in both machines, how will be activated the program with just one validation key in 2 machines.

 

the guide is not that complete, any help in hot to install it in 2 pcs?

Because the Display Unit does not require a key to function but the data provider does.   Install the Data Provider on your FSX machine and register it there.    Load the Display Unit on your laptop and set it up to connect to the Data Provider on your FSX machine and enjoy this essential FSX program.   I cannot imagine flying without it now.  It is immensely helpful, especially when flying on VatSIM.

The validation key is only required for the the data provider on the FSX machine.  The display unit on a separate machine doesn't need the validation key.

 

Cheers
