It is possible to have a license "EngardePro" and licenses "Display" or several licenses "EngardePro" on a computer. In this case, the first Engarde or DiapoEngarde application launched on this computer can distribute licenses for Engarde, DiapoEngarde and ShowPiste to other computers on the local network. On these computers, you have to do "Mode | Set PRO Mode" to ask for a license.
The "Keys | See the keys" menu allows you to see the keys installed on the
computer with their status (valid, outdated, bad key).
It is important to have a correct date and time on the computer. In the
case of an incorrect date, licenses can stop functioning. The "Keys |
See the keys" menu allows to see the reference date of Engarde.
Normally, it is identical to the computer date. When this is not the
case, a change of the date has been done on the computer. In that case,
it is recommended to set the correct date on the computer and to
perform a synchronization (menu of the window of the keys) to have a
verification of the date on the Web.
The licenses are placed in keys which are automatically
installed on the computer with the menu "Keys | Install a key". A key
contains pieces of information of the computer on which "Keys | Install a
key" has been performed; it cannot be moved to another computer except
with the license distribution mechanism described above.
