This concurrent user license is also called floating license. It is checked, how many users have started the Multimedia Player at the same time.
The license per Concurrent User combines the PC name + Windows user name (e.g. OFFICEPC-TOM) and stores this name in the license file. The combination is necessary to count a license, even if a user is logged in with the same name on multiple PCs.
Once the Multimedia Player is started, it checks whether the name is already stored in the license file and if not, it starts only in case a free license is available. After the Multimedia Player has been terminated, the license is given back by removing the name in the license file. The license will be available again for another user.
This license type can be used only for a network installation.
All files have to be on the server in the same directory - see files for distribution
If a user connects through a remote connection using a tool like Remote Desktop, Citrix, Terminal Server or gotomypc, it depends on the tool if the remote connection counts as a separate license. For most tools, Multimedia Protector retrieves the PC name of the remote PC and counts the connection as a new license.
