Hello azizi_lazard1988.

What is the bit version of the Lazarus you're currently using? I mean is it 32-bit or 64-bit? To find it, on Lazarus main menu > click Help > About Lazarus.

If you're currently using 32-bit version, then you may need to prepare your FPC to cross compile Win64. You can find more info on this wiki page, especially on the topic "From win32 to win64":
