You cannot install directly to ProWMC using just a ProWMC key. You have to first install Pro, activate it, then upgrade to ProWMC and activate. Then you can save the activation files (C:\windows\system32\spp\store\2.0\data.dat and tokens.dat) On fresh install, you overwrite the old data.dat and tokens.dat and set your product key.
I don't have a genuine key, can't I activate for now at all? Is there'nt another way? Sorry, I don't know how to mask so I replaced with x.
Thanks a lot looks like i am going to re-install but I didn't understand saving activation files? I dont have any backed up because I had not installed any windows 8 or 8.1 before please give me a sequence of fresh installation.
Thank you but Can you link me the post of correct procedure please. I just read a lot of threads and I am so confused
I'm not being coy man. You really have to do them in that order. There's no trick about it. There's no way around the legit activation method to generate legit activation files.
i have the same problem, my 8.1 pro cannot be activated, then I add WMC key and it accepts to upgrade, but then it's still un activated. Now, any key added come to the same result: This is None Core edition, the key is invalid, the Office is also
Do this (tried few nights ago and it still works): Grab one of those untouched Win 8.1 Pro RTM ISO files. Burn them onto a thumb drive or in an empty DVD disk. Install using generic key for Win 8.1 Pro. Afterwards, install one of the pastebin key using slmgr -ipk YOUR-PRODUCT-KEY-HERE Disconnect from internet, and type slui 4 select United Kingdom. Reconnect to the internet and call Toll-free UK number via Skype. Follow instructions and followed by enter your ID you get underneath the UK Toll-free number. Once done filling the required fields, it'll then, give an ID and some more instruction. Success! Note1: Do NOT, I repeat DO NOT skip any instruction if you're not familiar with this process. Note2: Do NOT make too many mistakes; though, if you've difficulties hearing the code given by the machine, you can use the repeat options as many times as you like. Additional steps: If you already have a LEGIT M$ Windows Media Center promotional key, it'd be icing on the cake! Install that feature with the help of said key and if it says "not activated", simply click "Activate" button and you'll be activated. All the best, and don't forget to backup your activation for future use.
