Hi,
Activation Error 0x8007007B means The File name, directory name, or volume label syntax is incorrect.
The following steps are solution:
Using the key provided to you (MSDN etc.) you will need to run the following in an
elevated command prompt –
if you are new to Windows 8, click Start –> type “cmd” –> right-click on a command prompt and select “Run as administrator” in the bottom of the page:
Next type the following commands:
slmgr.vbs /ipk XXXXX-XXXXX-XXXXX-XXXXX-XXXXX
slmgr.vbs /ato
The first command will update the key.
The second command will activate Windows.
Replace the "XXXX" bits with your Windows 8 Key (you do need to enter the dashes and you don't need to surround it with double quotes).
In addition, you can also check this article for reference.
