The standard distribution of FlexPDE will run in Lite mode when no Professional license is present. The Lite mode is restricted in the number of nodes and simultaneous equations a problem can have. In order to enable Professional mode and create larger problems, FlexPDE will need to be registered to a professional license. There are several forms for the license :
The standard method of licensing FlexPDE Professional is by internet activation. This mode of licensing generates a text key that locks the execution of FlexPDE to a specific computer. Access to the internet is required on a periodic basis to validate the key. The key can be released from one machine and reactivated on another without difficulty. If you need to use a proxy server for internet access, you can set this information on the Web Proxy Settings preference tab. A serial number will be sent via email. Use the serial number to configure the license in the License Registration preference tab. See "Internet Key Registration" for details.
On request, Professional configurations can be licensed by use of a portable hardware license key (dongle). The standard dongle for use with FlexPDE 7 is a Wibu USB Cm Stick. Unlike the dongle used by previous versions, this dongle can be used in local or network mode. See "Dongle Registration" for details.
In order for FlexPDE to find the dongle, you must
1) Run the appropriate dongle driver install program to load it into your system.
2) Install the dongle in an appropriate USB connector or hub. (Note : On Windows, an autoplay window may appear. Simply dismiss it.)
3) Register the dongle in the License Registration preference tab.
The request for a dongle 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 dongle. If a license is successfully acquired, the corresponding license class will be appended to the main window's title bar. The acquired license will be held until the current invocation of FlexPDE is terminated or two hours of idle time has elapsed. 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.
The primary use for the software key is for trial usage prior to purchasing a Professional license. On request, Professional configurations can be licensed in the form of a text key that locks the execution of FlexPDE to a specific computer. This license method has been superseded by the Internet Key method and PDE Solutions strongly encourages users not to use this method for a permanent license. If you prefer a software license key, you must first download and install the software and record the computer ID from the License Registration preference tab. Include the computer ID on the license application form. Your software key will be sent to you by Email. Save the key and configure the license in the License Registration preference tab (you may need administrator privileges to do this). See "Software Key Registration" for details.
