The Floating License of ExtendSim is typically installed in an environment where the Client device is used by only one person. This works well for academic institutions where students and professors install ExtendSim on their own computers (the Clients), such that it can be used on the network or checked out (roaming) for up to 30 days.

However, if ExtendSim is installed in a lab environment where multiple people log in to use the same computer, the user-modifiable files (example models, libraries, etc.) must be installed to a location that all the students can access. To do that:

As you install on each multi-user computer, when you get to the installer’s Installing User Documents section, select a location on the target machine that the students will have read/write access to. For example, you might select "C:\Users\Public\Public Documents" as the Destination Folder when you are at the Installing User Documents section. This will install user-modifiable files at the root of the C drive.

When you activate ExtendSim, copy the license file (extendsim.lic) to the folder selected in the User Documents section of the installer. In the example, this would be "C:\Users\Public\Public Documents\ExtendSim10."

Give the Users group full (not just read/write) access to the folder that has the user-modifiable files.

Note: at the end of their sessions, students should save their models (.mox) files to locations where other users won't interfere with and/or copy their work. However, they should use a local copy while doing work. Models will run slowly if they reside on an external drive or in the cloud.
