Recently encountered winEdit7 over the trial period of the problem, found the next solution.
This is achieved by automatically deleting the registry information on each exit to achieve unlimited trial purposes:

1) Open option "option Interface" "Advanced Configuration" "Event Handlers" "EXIT;
2) Add the two lines of code before end:
Regdeletevalue (' HKEY_CURRENT_USER ', ' Software\winedt ', ' Inst ');
Regdeletevalue (' HKEY_CURRENT_USER ', ' Software\winedt 7 ', ' Inst ');
3) Restart can be used indefinitely (pro-Test available)
WinEdt Exit (Cleanup) Macro closeappl ("YAP"); Close YAP if running ... CLOSEAPPL ("complete"); Close complete Wizard if running ... Regdeletevalue (' HKEY_CURRENT_USER ', ' Software\winedt ', ' Inst '); Regdeletevalue (' HKEY_CURRENT_USER ', ' Software\winedt 7 ', ' Inst '); End;
There is also a crack method, feeling that it is not convenient, and may be a period of time after the prompt registration.
