Individual & Node-Locked Licenses

Yes. Individual licenses can be installed on virtual machines (VMs), but will not launch unless activated. Permission must be granted within the Activation Key (AK) to run on a VM. The end user’s username on the VM they are installing ExtendSim on is required to grant permission for launching on the VM through its AK. If you are installing ExtendSim on a VM, contact the ExtendSim Sales Team to provide them with your Activation Key and username for the VM.

AND be sure that:

• The virtual machine has the correct permissions so that ExtendSim can be installed without security issues.
• The location where user-modifiable files will be installed has read-write access so ExtendSim can read the license file and the end user can open, run, and save models.
• And, be sure you use a static MAC address. The license file (extendsim.lic) relies on the identity of the device it is installed on. If a device's MAC (media access control) address changes, its identity changes, the license fails, and ExtendSim stops working. MAC address changes can happen if the Ethernet card or WiFi card is changed, or if the device is a virtual machine (VM) that uses dynamic MAC addresses.

Some hardware virtualization products, such as Microsoft's Hyper-V, create virtual machines (VMs) that, by default, have dynamic Mac addresses. For ExtendSim to work properly on a VM, the device must use a static MAC address. If the device automatically uses dynamic MAC addresses, you must change the settings in the VMs Manager so that the device uses a static MAC address.

You might not see an issue unless the device restarts and chooses a different MAC address, and all of a sudden ExtendSim reports that it isn't properly licensed. If you've experienced this failure, change the device to use a static MAC address. Then contact our Sales department so you can reactivate and get a new license file.

Note: The Trial version of ExtendSim cannot be operated on a virtual machine or on a Macintosh running Windows through Parallels or similar emulator until it has been activated. Only activated licenses will run on VMs.

No. Both licenses can easily coexist on a single machine while you transition your models to the new release.

1. The renewal date for your license’s Maintenance and Support Plan (MSP) is shown on the ExtendSim startup screen ( use the menu command Help > About ExtendSim to view the startup screen). Prior to the renewal date, the application will occasionally present a reminder message upon launch.
2. MSP can be renewed in the ExtendSim Store or by contacting the ExtendSim Team or local ExtendSim Distributor.
3. After renewing the MSP, your license file (extendsim.lic) will need to be updated by reactivating ExtendSim. After we notify you that the change has been made to the License Management System and the license has been updated, you will need to reactivate your license. See the document titled Reactivating • Individual & Node-Locked Licenses for more details.

Note: Not applicable to Student licenses.

Reactivation is required under the following circumstances:

• The Maintenance & Support Plan (MSP) has been renewed.
• You've purchased the ability to launch more than 4 instances of ExtendSim.
• The maximum number of Reliability Event Cycles has been increased.
• Substantial changes have been made to your device (such as a reformatted hard drive) that ExtendSim no longer recognizes itself as being validly activated.

DO NOT reactivate ExtendSim if you are merely updating to an incremental release of ExtendSim (e.g. from 2024.Rx to 2024.Ry).

For complete details on reactivating, see the document titled Reactivating • Individual & Node-Locked Licenses.

Moving ExtendSim from one device to another works the same as for most applications.

• First, make copies of your ExtendSim models, any custom blocks, etc.
• Remove the license from the previous device using the Help > Revoke License command.
• Then follow the instructions to Uninstall an Individual License of ExtendSim.
• Install ExtendSim on the new device by downloading the appropriate Trial version.
• Paste your model files, etc. from the previous device to the new installation of ExtendSim.
• Launch ExtendSim on the new device and activate it using the same Activation Key you used for your initial installation. (If for some reason you weren’t able to deactivate ExtendSim on the previous device, you will get an error message stating your Activation Key is already in use on another device. In this case, contact the ExtendSim Team.)

1. Before uninstalling ExtendSim, be sure to revoke the license using the Help > Revoke License Activation command.
2. After the license has been revoked, use the Windows Settings > Apps and Features to uninstall ExtendSim.
3. Finally, delete the two folders: Documents\ExtendSim and Program Files\ExtendSim. (The remaining contents of these two folders were created after installation. The uninstaller couldn't remove those files because it didn't know about them.)
4. If you're transferring the license to a colleague, see Moving or Transferring ExtendSim from one computer to another.

Note: These instructions are for ExtendSim Individual licenses only.

The ExtendSim installer is not an MSI installer but rather an InstallScript installer. Consequently, we don't directly support silent installs. One option is to do the following:

1. Take an image of  the device that does not yet have ExtendSim installed.
2. Install, but do not launch and do not activate, ExtendSim on that device.
3. Take a second image of the machine.
4. Create your own silent installer by using these two images to see how our installer altered the clean machine.

Note: The device you're installing ExtendSim on will need to have its own ExtendsimDocPath.txt file located at Program Files/ExtendSim. This text file contains the path to the Documents folder that contains ExtendSim user-modifiable files (Documents/ExtendSim).

When installing on a device that does not have internet access for an automatic activation, do a manual activation. The way manual activation works for an Individual license is:

1. Install the Trial version and launch ExtendSim.
2. In the Activation Dialog that appears, click the Activate button.
3. Since your device doesn't have internet access, ExtendSim will give you an error message "Unable to perform automatic activation".
4. In the error message, click the button to Save Activation Info as Text File.
5. You can choose where to save the text file; by default the file (ExtendSim Activation Info.txt) gets saved to the top level of the Documents folder.
6. Print the text file or write down its contents.
7. Using a device with email access, email the text file contents to us at Sales.ExtendSim@Andritz.com.
8. Using the information from the ExtendSim Activation Info.txt file, we will generate a license file (extendsim.lic) and email it back to you.
9. The only "tricky" part is getting the license file to the device that's on the closed network. Everyone does this differently, but the best way is to transfer the license file using a USB drive or other removable device or print the license file and take the printout to the device on the closed network where ExtendSim is installed. On that device, open Notepad and enter the information from the printed license file. Save the information as a text file named extendsim.lic.
10. Put that license file (extendsim.lic) into the UserName/Documents/ExtendSim folder (with Admin privileges if required) and relaunch ExtendSim.
11. ExtendSim should launch as an activated license. If the Activation Dialog appears, you've done something wrong.

For complete details on manual activation, see the Installing & Activating • Individual Licenses document.

 When you activate an Individual license of ExtendSim, you generate a license file (named extendsim.lic) that automatically gets placed in your Documents > ExtendSim folder. This file describes the license granted to you.

You can open the license file and see its contents, but you should not make any changes to it or ExtendSim will no longer launch. The contents of your license file will look similar to this:

LICENSE extendsim expro24ind 2024 permanent uncounted
  hostid=rehost=26f258g037e9323c36a4c8b6342cab6cbf694d4e
  issued=1-jan-2026 akey=1234-5678-9098-7654 options=m02/01/2027
  disable=TerminalServer _ck=3284946ad4 sig="60P04KD6DFY3GJ1N7KFUQJS51T
  JSBJ7HY8Y7KXS3KAFKD8HRG4GV022HT6ETDXS0MBW6MNEEAC"

Let's break it down line-by-line to learn what each item means:

LICENSE extendsim expro24ind 2024 permanent uncounted

• The LICENSE line defines the usage rights to a product.
• extendsim identifies the name of the product for which license rights are being granted.
• expro24ind is the Product Definition that ExtendSim needs to acknowledge which package you've purchased. In this example, it shows this package is ExtendSim (ex) Pro (pro) release 2024 (2024) and is an Individual (ind) license.
• 2024 identifies the release number.
• ExtendSim 2024 is a perpetual license so is considered a permanent license.
• uncounted ties ExtendSim use to a specific computer (the "node") and allows unlimited copies or instances of ExtendSim to run on that single machine to take advantage of Multicore Analysis.

 hostid=rehost=26f258g037e9323c36a4c8b6342cab6cbf694d4e

• This line is used for license locking.
• rehost means you have the ability to delete your license on one device and move it to another device.
• The hostid at the end of the line specifies that the licenses can only be used on the specified host.

 issued=1-jan-2026 akey=1234-5678-9098-7654 options=m02/01/2027

• The third line contains optional license parameters.
• The issued date is the date the license is activated.
• akey identifies the Activation Key assigned to your license.
• Options specifies unique settings in your license.
  • m/02/01/2027 indicates the date the Maintenance & Support Plan is up for renewal.
  • If you have purchased the option to launch more than 4 instances of ExtendSim, options would also contain n8 or n32 whichever you purchased.
  • If you also see r1000 or r10000000, it means you have added up to 1000 or unlimited Reliability Event Cycles (RECs) to your ExtendSim Pro license. 

disable=TerminalServer _ck=3284946ad4 sig="60P04KD6DFY3GJ1N7KFUQJS51TJSBJ7HY8Y7KXS3KAFKD8HRG4GV022HT6ETDXS0MBW6MNEEAC" 

• disable=TerminalServer disables the license from being used on Windows Terminal Server, a Virtual Machine (VM), and using Remote Desktop to access your license. If you are using ExtendSim on a VM or need to install your license on a separate device and remote in to that device, this option can be overridden by adding your username to the license file. Just contact us to request this.d
• _ck= is the license line checksum. A checksum is a small, fixed-size value calculated from a block of digital data, acting like a digital fingerprint.
• sig= is a unique signature line indicating the license has been signed by the license management system.
