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.
How you update your license depends on which product and release you are currently using. Choose About ExtendSim under the Help menu to open the ExtendSim start up screen. The bar at the top shows you which ExtendSim release you are using. If it does not say ExtendSim 10.0.8, you should download the most current release.
Updating from ExtendSim 10.0.4 or later...
If you are currently using 10.0.4 or later of ExtendSim Pro, DE, CP, Student, or Analysis RunTime, download the updater to ExtendSim 10.0.8.
Updating from ExtendSim Pro, DE, or CP 10.0.3, 10.0.2, 10.0.1, or 10.0.0...
The Trial version of ExtendSim is the updater. Download the appropriate newer release of the Trial version of ExtendSim 10:
Install the Trial version OVER the current installation using the same name and installing to the same location as the current installation. This updates ExtendSim without affecting the license file. When you restart ExtendSim, you will be running 10.0.7.
Note: If you subsequently launch ExtendSim and get a message that the license has not been activated, it means that you have not installed over the current installation but in fact have two installations of ExtendSim. Uninstall the update and reinstall it so that it replaces the files at the current location.
Updating from ExtendSim Student or Analysis RunTime 10.0.3, 10.0.2, 10.0.1, or 10.0.0...
If you are using ExtendSim Student or Analysis RunTime released prior to 10.0.4, contact Imagine That Inc. to obtain the newer release.
The renewal date for your license’s Maintenance and Support Plan (MSP) is shown on the ExtendSim startup screen (Help > About ExtendSim). Prior to the renewal date, the application will occasionally present a reminder message upon launch.
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 Analysis Runtime or Student licenses.
Before uninstalling ExtendSim, be sure to revoke the license using the Help > Revoke License Activation command (or the Help > Deactivate ExtendSim command if prior to 10.0.5).
After the license has been revoked, use the Windows Settings > Apps and Features to uninstall ExtendSim.
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.)
Since you will probably not be able to access the internet to automatically activate ExtendSim, follow the instructions for Manual Activation of ExtendSim in the Installing & Activating • Individual Licenses document. How you transfer the required activation information between your device and us depends on your normal processes.
When you click the Save Activation Info as Text File and generate the text file ExtendSim Activation Info.txt, save the file to USB or removable media, or print or copy its information. Email the file or information to .
When we email back the license file extendsim.lic, save it to a USB or other removable media, or copy or print the contents of that license.
Use removable media to copy the license file onto the secure device. Or use the information from the license file to create a text file on the secure device (use Notepad or right-click on the desktop to create a new text document); name the text extendsim.lic.
Place the license file in the folder that contains the user-modifiable files (by default, UserName\Documents\ExtendSim).
Restart ExtendSim. If the Activation Dialog appears, there’s been a mistake and the license hasn’t been activated.
