ENERCALC has never used copy protection in our software products, but we do employ a limiting system that monitors execution of the program. Your purchased software license allows for a specified number of SIMULTANEOUS users to be using the software.

 

The Structural Engineering Library contains programming that records information for the computer currently using the software. Based on the number of licenses allowed (which is encrypted into your Product Activation Code) the software limits simultaneous usage of the software to the number of licenses you have purchased.

 

What this means is that if you have just one software license, trying to start another program session with one already in progress will result in a message saying the second session is not allowed to begin until the first is terminated.

 

If you have any problems getting full simultaneous execution of all licenses you have purchased:

 

Make sure all currently running copies of the Structural Engineering Library are closed.

In the installation directory for the software locate and delete the file LIMITER_.EC0.

 

This file contains the usage information that the software thinks is currently running. This file will be created again automatically the next time it is started.

 

Note! Do not delete this file when the software is in use. If you do this then the software currently running will close down shortly thereafter.

 

To access the Network Limiter control screen use the "Settings" main menu selection -or- press the [Tools & Settings] button and select "Settings". When the Settings screen is displayed select the tab titled "Network Limiter Information" as shown below....

 

 

This screen provides two control items that you can modify:

 

System Signals Activity Every XXX Minutes

This controls how often the program updates the file that tracks all the users. Setting it to a higher value results in better performance.

 

Inactive Shut Down Time

This values is the number of minutes a running copy of the Structural Engineering Library can sit untouched (meaning no data entry, tab changes, button presses, etc) before it will be shut down when another user tries to start a session.

 

This item provides automated management of multiple usage needs when some users leave the software running and have forgotten to shut down.

 

Display a List of Current Users

 

This button displays a list of all computers currently using the software. The "Computer Name" field in the list is the computer's name reported by the operating system of the client computer (not the host) that launched the software.

 

 

Using this screen you can selectively delete users as needed.
