or you can go with advanced techniques like checking for hard disk serial number, processor ID etc..

Installing :
******************************************************************************
Request all Disk info
(using http://www.codeproject.com/KB/cs/hard_disk_serialno.aspx)

Add Date Of installation +30 days

Save data in Licence file (Decrypted with own decrypter/Encrypter)


Licence Demand
********************************************************************************
Give user possiblity to demand Licence : send  Licence file to you
Encrypt File :
Change Date Of Installation to today + 6 months
Respond with altered Licence file



You're program should check:
*************************************************************************
On startup :
Get Licence File
Request all Disk info
(using http://www.codeproject.com/KB/cs/hard_disk_serialno.aspx)

If Disk Info of x-1 on x of the Disks is OK (Can Occure that HD is changed otherwise all disks are OK)
So every disk must be the same only 1 may fail

Check date.

If in case 1 Disk Failed : rewrite Licence File :


This way the folowing check will not fail ;-)
and the user sees a changing licence File so he won't hastly edit in it


regards
poor beggar
