can't run any firemonkey app

hi guys.

i downloaded and installed Delphi XE10.1 Berlin, according to the instructions i saw here and in the Crack (version 2.4)
Delphi is running ok, but when i want to run a simple Android app i made as an example in firemonkey, i get an error :
"Android SDK tools are requierd.
Do you want to download and install Android SDK tools automatically?"
[Yes] [No]

if i choose yes, it opens a new window that try to download it from Embarcadero's site, and since i "didn't buy" Delphi, it says :
"invalid serial number"...


PLEASE HELP ME 

Thanks !
