To open the license registration dialog, click "Help" on the main menu bar, then click "Register". The following dialog will appear:
Computer ID
This field is the unique identification of your computer. It may be used to request a software key or Evaluation license for FlexPDE Professional.
Select a License Method
If your license has already been registered, this box will display the details of that registration. In the case displayed, a) the license method is by USB dongle; b) the dongle serial number is #200636f9.
If you are registering for the first time, you can select one of the three options: Dongle, Network or Key.
Dongle method
If you license is to be read from a locally attached dongle, click the "Dongle" button to select the dongle licensing method, then click "Read Dongle". FlexPDE will search the USB and Parallel ports for an appropriate license dongle. If no dongle is found, or if the dongle driver has not been installed, the search will fail, and FlexPDE will report an error.
Click "Register" to install this as the active license method. In future, every time you start FlexPDE it will search the USB and Parallel ports for the dongle.
Network method
If you select "Network", then "Register", FlexPDE will search your network for a running license manager, and return the status of that license.
In future, every time you start FlexPDE, it will expect to find a network license manager to grant licenses. In fact, the request for a network license will not be made until you actually "Run" a problem. At that time, a license of the appropriate class, 1D, 2D or 3D will be requested from the network. The acquired license will be held until the current invocation of FlexPDE is terminated. In this way, networks of FlexPDE users can get optimal use out of the mix of 1D, 2D and 3D licenses that have been purchased.
Key method
If you have copied your license key file "flexpde5key.txt" to the installation directory, this file will already have been read. Selecting "Key" will display the license key contained in that file. If you want to enter the keys manually, either type or paste them in the window provided.
Click "Register" to install this as the active license method. In future, every time you start FlexPDE, it will look for the license key file in the installation folder.
The "Read Dongle" button
This button will read the contents of the dongle without installing it as the selected license method. If you want to keep this selection, you must click "register".
License Features
This line displays the characteristics encoded in the license identified by the previous selections. In the case displayed above, the license encodes a four-user FlexPDE Professional license for 1D or 2D problems. Two of these four users can also run 3D problems.
