If you plan to sell your ebooks, HTML Executable gives you the option of turning your websites into trial ebooks. Trial ebooks may display nag screens at startup and can optionally offer limited trial periods or restrictions (10 days or 20 runs for example) to your future customers.

• HTML Executable has a flexible ebook licensing and DRM system: it comes with several tools to manage registered users of your ebooks, control who may access your ebook, deliver license or activation keys, block users when a purchase is fraudulent, and much more...

• Create and manage registration keys (a.k.a serial numbers) for users. A registration key allows an end user to turn your ebook from the Trial to a Registered version:

• Or unlock registered editions with online activation from your server or our Protect Ebook .net service. For advanced users, we provide the activation kit that allows you to install required files on your server and turn it into an activation server. For users who do not want to deal with PHP, server maintenance and installation, databases, Protect Ebook .net is a great deal.
   
• Protect your ebooks and intellectual property thanks to online activation. You can have your ebooks activated on a given number of computer(s) only, helping you to reduce ebook piracy. The activation process is easy and can be automated through the Internet, or Manual for end users who do not have a computer with an Internet connection:

• Registration keys can be created online or in mass: we provide scripts in php, C#, Pascal, VB... to all users of the Professional/Commercial edition. You can then integrate these scripts into your own sales system. Registration keys may also be manually created with HTML Executable.
   
• Easy integration with e-vendors such as PayPal, E-junkie, FastSpring: deliver ebooks and keys to customers by email immediately after successful orders. Our ebook protection service Protect Ebook .net offers hassle-free solutions available for less than 1 USD per day!
   
• Accept refunds from customers thanks to the Deactivation feature that uninstalls a registration key definitively from a computer and gives your customers a refund code that you can verify in order to refund them. Moreover, deactivation can be combined with online activation so that end users can transfer your registered ebook from a computer to another one, and without asking you for more activations!
   
• Block users who were refunded or illegal users from running your ebook thanks to the online key validation feature. At each startup or randomly, the ebook will contact your activation server to verify that the end user has still the right to access your ebook. If not, the ebook can stop or work in a disabled mode:

• Integrated DRM (Digital Rights Management): no external expensive solution is required.
  
  
• Show customizable nag screens at different times:

• You can select which HTML pages and/or PDF documents should be displayed only after user registration or depending on which edition the user purchased!
   
• You can put a link to your order page directly in the nag screen (actually anything you want).
   
• Use the key blacklist option for stolen or refunded registration keys:
   
  
• Create hardware-locked registration keys: the key you send to an user will only work on his/her computer. This will reduce piracy possibilities:
