WinLicense should do the trick.
Can't give you a warez link so just search for it yourself - or buy it.

when u pack, you could do like this:
pack with Themida without Patch Guard and pack with VMProtect again.
~OR~
pack with UPX and pack with UPX-LOCK (chinese hackers made) and obfuscate it.
OBFUSCATION ( OPEN WITH HEX EDITOR AND CHANGE UPX! and string upx version to 00 00 00 00 ...
~OR~
pack with VMProtect pack with NeoLite with Max Compression and pack with VMProtect and obfuscate it.
when u do in coding,
check PEB.BeingDebugged(=IsDebuggerPresent API)
use CheckRemoteDebuggerPresent
check PEB.NtGlobalFlags
use Windows SEH
check OutputDebugString
check Hardware Breakpoints
or others ~~

Everything he listed above can be undone and/or bypassed fairly easily.

Using anything premade will not give you much if any protection. Everything has a bypass or method to get around what ever it protects. The only method of protection that will pose any security is to make your own. Along with that, use multiple protections and not just one. Encryption, obfuscation, detection of debuggers etc will all help, but, unless you come up with your own things people will have methods are the ones that are already made.

Couldnt you in some way avoid the debuggers:
Code: | var
window: hwnd;
begin
window:= FindWindow(nil, 'OllyDbg');
if window <> 0 then
begin
showmessage('OllyDbg detected, shutting down');
application.terminate;
end;
end; |
Add that to a timer, and there you go
well, i guess you could crack that easyly aswell, when you open the .exe in Olly...
