As explained in other threads in the forum, the latest version of our software for P3D is now 64 bit, which means it doesn't support Esellerate activations anymore, since there's no 64 bit version of Esellerate and there never be one, since Esellerate closed in 2019.
We switched to QLM/Soraco before Esellerate closed, but we kept Esellerate in the software, in order not to force everybody to reactivate everything on that day, assuming that, after an hardware change or a Windows reinstall, you would require a reactivation anyway, so we waited more than a year before removing Esellerate from the software, but we couldn't delay the switch much further, since it prevented to create a more reliable 64 bit version of the program.
You only need to reactivate your existing key and you can even use your old Esellerate key, since when migrating all our old Esellerate keys to Soraco, a new Soraco key has been automatically associated to your existing Esellerate key. Our software can use both, but it must be online for the old Esellerate key to be accepted.
In some cases the firewall will prevent our software to access to the activation server, so the QLM "License Wizard" will appear, and this only accept the NEW kind of keys from QLM/Soraco, which are those that starts with an "A". In this case, you should use the QLM Self-Help site linked on our FAQ page:
https://qlm1.net/virtualisoftware/qlmcustomersiteAnd use the "Email License Keys" option to retrieve the new keys associated to all your past orders. Use these ones to activate all your products that need activation.
