Merge licence file with dll.

Hi ......
I am using aspose.dll in my application. I am puting dll and license file in application directory. 


My problem is that :- if I keep license file with dll then anybody can use my license.

Expectation:-   I want to keep license file hidden or merge with dll.  So no one can s use it.

Please help me for merging license file with dll or Please can you send me a dll witch not need license file. (witch will take licence key hard-coded in constructor  )

Thank you.
