Delphi + DCPCrypt 2 (RC6) vs RAD Studio + DCPCrypt 2 (RC6) = KABOOM!

You also use actcode := in your code, but actcode is no variable parameter. You overwrite it before evaluating the value which was passed to the procedure.

Now I understand what you were saying. licdata[] IS initialised with values...the assignment is not reported to not prolong the code too much... you have a PM with real routine.

Nope...I use the code suggested to decrypt or encrypt a string in the html help files bundled with the control. The code is not part of DCPCrypt 2 itself but it is suggested in the help file... (i did copy/paste...and it works perfectly in other delphi versions prior to unicode ones).

The BIGInt is only FGint renamed to fool some automatic scanners.
