Protection

Password Protection is a SIMUL8 Professional feature.
The simulation can be protected so that it can be opened and run, dialogs can be run, results can be inspected but objects cannot be moved or their properties accessed.

To protect a simulation go to the Information section of the File Tab. Once the password is set it cannot be removed without the password. If you forget the password there is no way to rediscover it.

Check the check box to “Protect All”.

Once the simulation is saved, closed and reopened the simulation is protected.

To be able to access the simulation in unprotected mode go to the Information section of the File Tab. Enter the password and click OK then click OK again. The simulation is now open to full access until it is closed and reopened.

To remove a password go to the Information section of the File Tab, enter the password, click OK and then delete the password from the box where it was originally typed. Then click OK.

To remove protection from a simulation without deleting the password (so it can be reused later) go to the Information section of the File Tab and enter the password, then uncheck the “Protect All” check box and click OK.

If the simulation is saved, closed and reopened then full access is available.

What happens with old versions of SIMUL8 (file compatibility)?

All SIMUL8's from version 5 onward are file compatible but SIMUL8's before R7 Build 184 did not support the hardware key. For this reason, and to prevent unauthorized access to protected simulations by use of old SIMUL8's that are file compatible, all simulations that contain security information are made incompatible with older editions.

If you see “Not a SIMUL8 file” or “File corrupt use backup” when opening a simulation in an old SIMUL8 it may mean that the file is protected with security. If you need to open the file in an old SIMUL8 you must first use a new SIMUL8 to open the file, remove the security protection, save it and then use it in the old SIMUL8 (this will require knowledge of the password).
