I can’t get the Design-time package of Alpha Controls 17.10 to install in Delphi12 (community Edition). The run-time one was OK. I then opened acDX12.dpk, right-clicked on its .bpl in the Project Manager window and clicked Install, but it failed – the fail line is {$IMPLICITBUILD OFF} . Tried Build instead but that failed too.
What am I doing wrong?
