• Data Execution Prevention (DEP) • If ExtendSim fails on launch with Unknown message or fails when placing a block in a new model with the Unknown block message, it is probably due to a Windows security feature called Data
Execution Prevention (DEP).
• DEP can help prevent damage to your computer from viruses and other security threats. It does this by stopping
the execution of potentially malicious code from the DATA segments of memory.
• ExtendSim has an integrated compiler, so it creates and executes compiled code from the DATA segments of
memory when it runs. Depending on how it is set, DEP can interpret this as malicious data, rather than legitimate code, and stop ExtendSim from properly launching (by giving an Unknown msg error) or prevent it from accepting a block in a new model (by giving an Unknown block message).
• To access DEP:
• Go to the System & Security or Maintenance in Windows Settings.
• Click System, then go to Advanced System Settings.
• Under Performance, click the Settings button and select the Data Execution Prevention tab.
• Since many legitimate applications execute code in the DATA segments of memory, Windows has two methods for allowing applications to be exempt from DEP restrictions:
• The default setting for DEP is "Turn on DEP for essential Windows Programs only." If DEP is in this mode, ExtendSim will run properly.
• The higher security setting for DEP is "Turn on DEP for all programs and services except those I select". If DEP is in this mode, it will interpret ExtendSim as being a potential threat and prevent ExtendSim from properly running unless ExtendSim is added to the list of exempted programs. To add ExtendSim to the list of programs that allow Data Execution, find the DEP dialog and add ExtendSim.
Reprise License Manger (RLM)
Already Installed on Server
When RLM is already running on the Server where you want to install the License Manager for ExtendSim
DO NOT use the installer named ExtendSimServerLicenseManager unless instructed below.
The Floating license of ExtendSim uses the Reprise License Manager (RLM.exe). If RLM is already running on the Server where you want to install the License Manager for an ExtendSim license, there are two options:
Case 1 • If the currently running version of RLM is release 12 or greater, use Case 1, below, to add ExtendSim files to the existing installation.
Case 2 • If the currently running version of RLM is earlier than release 12, use Case 2, below, to stop and remove the existing Service and instead use the RLM.exe that ships with ExtendSim.
Case 1 • If the currently running version of RLM is release 12 or greater
Step 1 • Install the ISV Settings File on the Server
1. DO NOT INSTALL THE EXTENDSIM LICENSE MANAGER ON THE SERVER.
2. Obtain an ISV settings file (extendsim.set) from Imagine That Inc.
3. Place the extendsim.set file in the same directory where the other RLM-using product has installed RLM.exe
and their license and settings files. Step 2 • Activate the License
1. Follow the instructions for Step 2 • Activate the License Manager in the document Installing & Activating ExtendSim Floating Licenses.
2. Activation will either be automatic or manual.
3. Make a copy of the extendsim.lic file for use in activating ExtendSim on each Client device.
• Since RLM was already running, the extendsim.lic license file will be located in the same folder where you placed the extendsim.set file.
• If you subsequently edit the license file, such as changing the ISV port, distribute the modified file to the Clients. - 7-
