if you only provide .dcu, .bpl or .exe then you don't need source code protection
otherwise just zip it with a password

why make it complicated ?

Ok, my question has been not  that clear :

on a first stage I want to protect my code with a license file , run the app only with a valid serial nr. and until a certain date -   should be a first step for application protection ---

next step - soneone going to my hack my ( *.exe) - bypass the license file issue  - the mxprotection   http://delphi.about.com/od/productreviews/l/aa022503a.htm   seems to be a solution- but could not fond mxprotection as free code or as a component for D2010 at all

Hi BdLm

First check my answer here:

It will give you some hints.

Now to protect the software with a free application that will produce a serial and has time limitations..
If you dont care about the nag screens then you can try :
ExeCryptor (http://www.strongbit.com/execryptor.asp)
AsProtect (http://www.aspack.com/asprotect.aspx)
Themida (http://www.oreans.com/)

Keep in mind that there is NO free packer that will meet your needs :
1) Licence creation
2) Serial authentication
3) Time limit

The links above is as close as you can get.

Free packers are :
UPX (http://upx.sourceforge.net/)
MEW (http://www.softpedia.com/get/Programming/Packers-Crypters-Protectors/MEW-SE.shtml)
Win32 Intro (http://www.brothersoft.com/games/win32-intro.html)
Exe Stealth Protector (http://www.webtoolmaster.com/exestealth.htm)
Kkrunchy (http://www.farb-rausch.de/~fg/kkrunchy/)
UPack (search google)
XComp/XPack PE32 (http://soft-lab.de/JoKo/)
CExe (http://www.scottlu.com/Content/CExe.html)

The only protector that is 99% your solution is :
Exe Stealth - >
(minimum nag screens)...

Anti Cracking Protection
Full Software Licensing System
Polymorphism Engine
Metamorphism Engine
Bundle whole Application in an Unique Layer
Evaluation and Trial
Code and Resource Compression
Compatible with several Development Tools

Also check AsProtect...

Hope this helps.
