Permission and Location Issues for User-Modifiable and Other Files - continued
If ExtendSim reports a problem (such as “Documents folder not found” or “lp_solve...system error code: 2”) as it tries to launch or gives a similar error message when end users try to open model or library files:
• Verify that user-modifiable files such as examples and and libraries are installed in a folder that is accessible by the end user; by default, that folder is UserName/Documents/ExtendSim10.
• Check the permissions for the ExtendSim folder where user-modifiable files and extensions are installed. End
users need read/write or full access to that folder,
depending on its location, so they can open, run, and save models.
• So ExtendSim can properly open needed files, right-click its icon and select Run as Administrator as you launch it.
• If the user-modifiable files were moved after installation, modify the file ExtendSimDocPath.txt (located by default at
Program Files/ExtendSim10) to indicate the new location. Activation Dialog Issues
After you have activated ExtendSim, the Activation Dialog should not appear again spontaneously. If it does appear, it could indicate that:
• The license file (extendsim.lic) has been placed at the wrong location when you manually activated the software or has been deleted. Verify that the license file is in the ExtendSim folder that contains the user-modifiable files (libraries and example models); by default, that folder is UserName/Documents/ExtendSim10.
• There are multiple instances of the same ExtendSim product installed on your device. For example, you may have downloaded a Trial version of ExtendSim Pro to use as the updater for an existing installation of Pro. To properly update the existing files, the Trial version must be installed using the exact same folder name and to the same location as the current installation. If there are duplicate installations, uninstall the Trial version and reinstall it over the existing installation so that it updates the ExtendSim 10 files.
Other Issues When Installing or Launching ExtendSim
• In certain unusual cases, standard C runtime libraries that ExtendSim expects to find may be missing from your Windows operating system. In that case you will get the error message api-ms-crt-runtime dll is missing from the
computer when you try to launch ExtendSim. In this case you need to update your Windows operating system with the Universal C Runtime (CRT) component. See Microsoft support for information.
• In an ActiveX/COM client/server process, if a Client app tries to launch ExtendSim as a Server, you might get the error message Run-time error 429: ActiveX component can’t create object. This occurs when the operating system restricts ExtendSim from registering as an OLE/COM server. So ExtendSim can register itself as an OLE/COM server to interface with Excel and other apps, launch ExtendSim with Administrative privileges (right-click the ExtendSim application and choose Run as Administrator) so that it can complete the process of registering itself as an OLE/COM server.
Specific Situations to be Aware of
• Windows Defender Security Center • In addition to any installed virus protection apps, Windows 10 installs with a Windows Defender Security Center that has virus, threat, account, firewall, and network protection. So even if you have temporarily disabled your virus protection app, the Security Center could be blocking the installation or launching of ExtendSim. You may need to change the settings or set the ExtendSim installer to be excluded in the Windows Defender Security Center. Be especially aware of those settings if you are attempting to install ExtendSim on virtual machines using Windows 10.
