When activating MS Office 2013 on windows 8 Pro x64, I'm getting this error. Error code: 0xC004F074 The Software Licensing Service reported that the product could not be activated. No Key Management Service (KMS) could be contacted. Although I've synched my time, changed the IP + try to follow each step but I can't able to get activate. By the way, the activation goes smoothing on windows 7 Ultimate. Try to explain in simple detail cause I'm a total newb.
