To operate the [[SMath Studio]] program, you must obtain a license either from the [[Root Licensing Server]] or from the [[Local Licensing Server]]. It is important to understand you need a license even if you are using free version of [[SMath Studio]]. While obtaining a license, you may encounter one of the following challenges:

== Error message: Digital signature of the license contents has expired ==

If during the process of obtaining a license the [[SMath Studio]] displays the following message: "''Digital signature of the license contents has expired''" - this can only mean that the time between the computer acting as a server and the computer on which the copy of [[SMath Studio]] is installed does not match.

== Diagnostics ==

To diagnose this challenge you need to run the following commands in your command shell:
* '''For Linux''': command ''date'' in your terminal:
*: [[File:En_datetime_linux.png|250px]]
* '''For Windows''': commands ''date'' and ''time'' via command prompt or PowerShell:
*: [[File:En_datetime_windows.png|250px]]

'''Important Note:''' if you are using [[Local Licensing Server]] you need perform the same actions on the computer where the server is hosted! Your server time should match what you see on the computer where [[SMath Studio]] is installed.

Compare the results of running the commands on your server (if you have a [[Local Licensing Server]] installed) and client (where the problem with the [[SMath Studio]] software was detected) machines, and make sure that this time corresponds to the correct time in your region.

We strongly recommend to have a time server in your network, keeping your machines system time synchronized automatically. This will let you avoid any errors, caused by wrong system time configured.
