I bought 10 keys from a other vendor like gamers-outlet.
The first key worked there but after 1 month the other 9 keys didn't work anymore.

With keys from gamers-outlet i had zero problems! They just work.

Works Fine, At First Time Activated.

✔️Instalada sin problemas sin necesidad de reinstalar el sistema operativo.
????✖️???? recomendado.

Works fine! Perfect, thank you!

Bought a second key for my other pc, worked great
