Greetings, my friend!
You are wrong, the key can be used by calling Microsoft product activation support.
You need to contact a support operator, tell the person the installation code, he will dictate you the confirmation code to activate.
This key can be used 20 times to activate 20 PCs.
I used this key in full, the denomination was 20 online activations.
There are 20 offline activations left.
Get Web: Get confirmation ID on the website.
Call MS Support: Call Microsoft support via skype.
