Hello. I installed w8PRO retail, then enter XXXXX.J8CK4, then slmgr /skms ecc.ecc. then I attempt to activate with KMS several times, but no result. I used : 22.214.171.124:1688 win8kms4.mooo.com kms.creighton.edu:1688 lunar21.no-ip.org:80 I run cmd.exe as Admin, and I synchronized with time.windows.com both with fuse UTC+1(Rome) and UTC+2(Cairo) but it is impossible to connect with the server : the returned error code is always 0xC004F074 I attempted to execute w32tm /resync but have error : the service is not running. I downloaded and installed VAMT 2.0 Volume Activation Management Tool and NetFamework 3.5, and granted connection in the Windows Firewall : but nothing. It seems there is not connections with the servers. I have received from M$ the code for WMC but I can't use it ! What can I do ?
