I have installed and connected the key of 2 pc that run under Windows 7 64 with 16GB of RAM. Why this description? Because the key does not work correctly under this version of Windows and with much RAM what another reviewer reported. I find myself much less stupid not to have succeeded in this key function normally.
I am very disappointed, I will try to exchange it with another product. There is not even a driver for a possible update to the site, it is shameful !!!
