License Code

For trial versions of ExpeDat, no license code is required, but you may only use the software for a limited time.  If you are installing a purchased version of ExpeDat, you will be asked to enter a license code when you first run each application on a new system.

Administrators can download license codes from the same secure customer site where the software is downloaded.  End users should obtain codes from their administrators.

License Configurations

Depending on the terms of your software license, you may be provided with multiple codes for some applications.  Different license codes may be configured to provide different default settings for your applications.

You only need to keep one copy of your software for each platform you use.  Each executable contains all of your licenses.

For example, each servedat server may have a different license code, each tied to a specific CPU.  You would copy the same executable to all of your servers, then enter a different license code for each one.  See Tech Note 0007 for more information about license binding.  Be sure to use the correct code as using the wrong code may cause the software to behave in unexpected ways.

Saving the License

After validating your code the application will attempt to save a license token.  Note that this token is specific to the CPU on which it was created and will not work if copied to other CPUs.

On unix systems, including Mac OS X, the license token will be saved in ~/.dei-mtp and copied into /etc/dei-mtp if this file is writeable.  Placing the token in /etc/dei-mtp registers the application for all users of the system.

For Administrative users on Windows systems, the license token will be saved in the system registry under the root class dei\mtp\.  For Limited users, or if the registry is not writeable, the token will be saved to dei\dei-mtp.dat in your Application Data folder.

Note that if you change your hardware configuration, you may be asked to re-enter your license code.  For example, the first time you switch from an ethernet to a wireless network, you may need to re-enter your code.

If an application repeatedly asks for a license code, check the locations cited above, including the Windows registry if applicable.  If tokens already exist in one or more of these places, delete the token for the affected application from each location and try entering your license code again.  If your license includes multiple codes, make sure you are using the correct code for your location and the application you are registering.

Changing the License

If you need to enter a new license code for an application, the command line option "–R" will repeat the license code registration process.  For MTPexpedat, click the About button, then click on "Enter New License Code" to re-register.

About Your Privacy

Depending on your license and configuration, the application may send a single test message to one of DEI's servers when you register a new code.  This message contains only the public identification text that is available to any MTP application.  See Tech Note 0001 for an example of what this looks like.  No other data from you or your computer is sent.
