This tutorial demonstrates how to implement Mobile
License and protect your mobile application as a trial (general evaluation)
node-locked license. Specifically, you want to distribute your application as a
trial version in which the user can try out the application immediately after
installation, without requiring an evaluation License Key. If the user wants to
continue to use the application after the trial period, you can issue the
License Key to turn the trial version into the full registered version.
Based on the settings used in this tutorial, the following describes
how the user would experience the protected application.
·
When starting the application, the
Registration dialog box pops up showing a Registration
ID. The user may click the Register Later button to skip registration
during the trial period.
·
The user can try out the application for a
limited trial period.
·
The user cannot gain additional trial period
by reinstalling the application or turning back the system clock.
·
To register, the user can contact you by
email, phone, fax, etc., and provide the Registration ID.
·
With the received Registration ID, you can
generate the License Key to be returned to the
user that turns the trial into full version (or extends the trial version).
·
During registration, you may collect the user
information and charge the user a license fee.
·
When the user enters the License Key in the
Registration dialog box, the application is turned into the full registered
version.
Note that the shell protection method does not support mobile
applications. To protect Windows Mobile applications, you can use the provided KeyCheck API (including
the KeyCheck Class Library and the KeyCheck .NET CF Component). Please see Protecting
Applications Using API and the provided code examples for more
information.
To create a setup package and distribute your application, please
ensure to include the protected version of your executable file and the ElecKey system file:
·
Ekc3220M.dll
(in \Deploy\MobileApp\KeyCheck\)
The above system files must be placed in the same directory as the
protected executable file. Please see Mobile
License System Files for more details.
By implementing Mobile License, you can license the protected
application by generating the License Key to be returned to the user. The following
instructions describe how to use LicenseKey Manager to generate a License Key.
1.
Run LicenseKey
Manager.
2.
In the Main tab of the Key
Properties pane, enter the Registration ID received from the user in the Registration
ID field. Then, click the Check button.
3.
The Identification field shows the Key
ID, Program ID, and flag decoded from the Registration ID. The flag M
means the Registration ID is generated from the Mobile Key.

From the Implementation drop-down
list:
5.
Select Distribution if you want to
generate the License Key that turns the application into the full version with
no limit.
6.
Select Evaluation if you want to generate
the License Key that extends the trial period. You can then specify the Expired
Date, Max-Day, and Max-Exec as you want.
7.
From the Note pane, you can enter
notes about registration such as the user’s name, address, telephone, etc. in
the Messages field.
8.
From the Email pane, you can enter the
user’s email address in the Email Address field.
9.
Click the Key Properties pane. Then,
