jean-paul_1 on after successful installation EZKEYS, where do I start the program ? I can't find it ?

Yes, afters hours and hours, last night, I finally succeed to install the programs in the application folder, except the EZkey's player as I told you before.
Of course, from the launchpad, I tried to open and to autorise EZKEY'S with my serial number but this number is refused.
At this step I can see that the window for autorisation is the window of EZKEY'S DEMO not the right one. ( I have no more EZKEY'S demo on my mac.)
