I installed new system on my pc.  When trying to start sabre squadron exe  the massage appear "Wrong cd key. Contact to illusion bla bla". I really don't wont to reinstall the game again? so is there any  way to fix it? Ive got proper cd key, but dont know where(in which file) to paste it manually, if its possible.

Start regedit (start -> run -> regedit -> enter) and check the key HKEY_LOCAL_MACHINE\SOFTWARE\Illusion Softworks\Hidden & Dangerous 2 you entered is the correct one

Your registry might look like this one (no idea about the vista/win7 registry settings):
