Question on Prior Releases • ExtendSim 10 & Older

If a Client device has checked a license out of an ExtendSim 9 Network license and cannot check it back in, they should be presented with an error message. If that error message states it is an undefined license, the registry keys ExtendSim uses to identify the license files has probably been trashed.

To resolve this issue, on the Client device, remove the lic.dat file from the Documents > ExtendSim9 folder. This will reset the Client device so it will no longer be checked out allowing ExtendSim to launch on that device and connect to the Server as it should.

This procedure will enable the Client to use ExtendSim, but it does not repair the missing license instance for the License Manager. It will still show the license count is down by 1. See the FAQ ExtendSim 9 Network Issue - Resetting the license count for the License Manager.

You will need to reset the ExtendSim 9 Network license's License Manager if there is a connection issue or if a user on a Client device has:

• Removed the lic.dat file from the Documents > ExtendSim9 folder,
• Uninstalled ExtendSim while a license was checked out and never checked back in, or
• Damaged a license so it can't be checked back in.

To reset the license count:

• On the Server, open the ExtendSim9Server folder (by default, it is located at the root of the C: drive).
• Right-click on the Remove ExtendSim9Server.exe file and choose Run as Administrator.
• Locate the file Setup ExtendSim9Server.exe. As was just done with the Remove file, right-click the Setup file and choose Run as Administrator.
  • During the Setup procedure, you will receive a Reference Code. Email that Reference Code from the Setup dialog with your ExtendSim 9 Serial Number to sales.ExtendSim@Andritz.com.
  • The ExtendSim Team will generate a License Key and email it back to you to complete the Setup process. It may take 24-48 hours for you to receive the License Key, so you can click Cancel to close the License dialog.
  • Once you receive the License Key, reopen the License dialog.
  • Enter the License Key in the appropriate field of the License dialog and click OK. You will receive the following notices confirmig the License Manager is setup:
    • License Key accepted.
    • The IP address of the Server. You will need either that IP address or the Server’s Domain Name to install and activate ExtendSim on Client computers.
    • Server License Manager Installed.
    • Server License Manager is running verification message.

To run ExtendSim on a Client device of an ExtendSim9 Network license, the Client must either be connected to the same network the License Manager is installed on or have checked out a license from the License Manager on a previous connection.

When launching ExtendSim on a Client device, if you receive the error message "This ExtendSim installation is part of a Network License. It must be connected to a license file on a server to operate.", there is a connection issue. Possible causes are:

• A firewall is blocking the communication between the Client and the Server.
• The IP address or Port number entered into the Client are incorrect.
• The License Manager on the Server is not running properly.

If the License Manager is not running properly, the end user might get an error reporting the Server is actively refusing the Client connection. In this case, you will need to reset the License Manager on the Server. See the FAQ ExtendSim 9 Network Issue - Resetting the License Manager on the Server.

To see the list of Client devices that have checked out and/or checked in a license on an ExtendSim 9 Network license:

• On the Server that contains the ExtendSim License Manager, open the ExtendSim9Server folder (by default, this is installed at the root of the C drive).
• Locate the WANExportLog.txt file.
• This file contains the historical list of licenses that have been checked out and checked in.

All ExtendSim versions are upwardly compatible. So ExtendSim 2024 will read in models built in ExtendSim 10, 9, 8, and 7. ExtendSim 10 will read in models built in ExtendSim 9, 8, 7, and Extend 6. And so on.

However, ExtendSim is not backwardly compatible. Models and blocks you build in ExtendSim 2024 cannot be read by earlier versions, such as ExtendSim 10 or ExtendSim 9.

If you receive an error message on your client installation when trying to check a license out of your ExtendSim 9 network license it is probably the result of not having sufficient permissions on your client machine to checkout the license. The checkout process requires some administrative rights on the client machine and many companies are restricting these rights from users.

Try using the right-click command Run as administrator. If this doesn't work, then you may not have been granted sufficient permissions by your company on the machine to check out a license.

For release 9, run the Remove ExtendSim Server.exe file in the Server’s ExtendSimServer folder. You should get two messages:

• License Successfully Removed
• Service Successfully Removed

Then use Windows Settings to uninstall the ExtendSim Server files.

Legacy libraries are older libraries that are no longer supported, could result in problems in new releases, and at some point will not be included with ExtendSim.

• Legacy files are only supplied for a limited period of time so that you can:
  • Open older models and hierarchical blocks that use those libraries.
  • Convert those models and hierarchical blocks to using the new libraries.
• During its history, the following libraries have been relegated to Legacy status:
  • With the release of ExtendSim 10, the Plotter library was relegated to Legacy status. The new Chart library in ExtendSim replaces the Plotter library. Convert existing models to using the new Chart library and avoid using the Plotter library when building new models.
  • With the release of ExtendSim 7, the following Extend 6 libraries were relegated to Legacy status:
    • Animation
    • BPR
    • Discrete Event
    • Generic
    • Manufacturing
    • Quick Blocks

NOTE: The current release of ExtendSim does not include these Extend 6 Legacy libraries. ExtendSim 2024 is NOT compatible with and does not support Extend 6 Legacy libraries.

• Check if exService is running as a Service. For Windows, look in Computer Management\Services and Applications\Services.
• Look in the Task Manager's Details tab. Both exServer and exService should be listed as running and both should list the System as the User Name. If the User Name for either of them is not System, the License Manager needs to be reinstalled.

When you open and convert a model that was built in ExtendSim 9, the converted ExtendSim 2024 or 10 model is not associated with a file association until it is saved. Data Import Export blocks use the model path name to resolve the relative file path name specifications. Consequently, Data Import Export blocks using relative file path names will not function properly until the newer ExtendSim model has been saved and is associated with its file.

Make sure that you SAVE the new ExtendSim model following its conversion from ExtendSim 9 before running it.

ExtendSim 2024 was released July 24, 2024. It's always best to use the most current release of any software, but there still might be a need to use a previous release for a short time period. For example, your colleagues are using ExtendSim 10 and you need to be using the same release for model sharing or your company still has an ExtendSim 10 Floating license and you need to install ExtendSim on your Client device.

The ExtendSim Team will continue to provide support to customers who are converting models and libraries from ExtendSim 10 to ExtendSim 2024.However, there will be no new bug fixes, security updates, or non-security updates for release 10. The final release of ExtendSim 10 is 10.1.1. If you are still using release 10, be sure to update to the final release.

Purchasing ExtendSim 10 products

For a limited time, ExtendSim 10 products are still available for purchase through the ExtendSim Store or from your ExtendSim Distributor. You are still subject to payment of the annual Maintenance & Support Plan based on the current price.
