Yo, so I've correctly downloaded/fixed my first D3 installation, now I opened the launcher and as the second one goes on, it just keeps itself at 0%. I've left it for an hour and a half and still no change.
I've directed the second installation to save in the exact same folder of the first one ''Diablo-III-8370-enGB-Installer''

And also at the start it told me that ''minimum specifications: Pentium D 2.8GHz or AMD Athlon 64 X2 4400+'' but my friend told me that he got the same message given he has a brand new computer and he just restarted D3 and it works fine for him. I haven't set my Game Key on battle.net but that's not keeping it at 0% either.

And another thing is my Windows 7 is fake, and although my friend told me that when he had it his WoW was buggy but my WoW works fine.

So what's the problem here? Thank you.
