Can you recommend any copy protection and license management solutions for
protecting my softwares ?

Users should have license for using programs according to their contract
days. ex. 180 days.

Thanks a lot in advance!

I wrote my own system.

Tools available from sites such as sysinternals.com can crack any
method you use to store a future date anywhere on a system such as in
the registry or a file. Unless it's encrypted. But even then if you
delete the date from wherever it's stored your app may think it's just
installed.

Thus I prefer to limit the number of records in one key table such as
5 units or 50 volunteers but allow unlimited access for everything
else. Once I get paid then I email them an encrypted file containing
the number of records they are licensed for as well as their company
name which goes on the bottom of every page of every report and
frequently used forms.

For more of my thoughts on this topic see the "Copy protection or how
to safely distribute a demo Microsoft Access Application" page at

This is why you don't put the entire encrypted string in one place. <eg>

True, nothing is truly infalable, but there are ways to make it so hard that
it just isn't worth the hack's time.

So what if you put the encrypted string in multiple places. Tools
can still read all those places.
