Cannot activate Windows 10 Technical Preview Enterprise build 9860 Error: 0x8004FC12 RRS feed

  • Question

  • I am unable to activate Windows 10 Technical Preview Enterprise build 9860. I receive Error: 0x8004FC12. I have tried one fix of manually entering the key and manually activating. Below is the result.

    C:\WINDOWS\system32>cscript slmgr.vbs -ipk PBHCJ-Q2NYD-2PX34-T2TD6-233PK
    Microsoft (R) Windows Script Host Version 5.8

    Installed product key PBHCJ-Q2NYD-2PX34-T2TD6-233PK successfully.


    C:\WINDOWS\system32>cscript slmgr.vbs -ato
    Microsoft (R) Windows Script Host Version 5.8

    Activating Windows(R), Enterprise edition (72e02447-a7bc-462c-9c3d-e5c919a5140a)
     ...
    Error: 0x8004FC12 On a computer running Microsoft Windows non-core edition, run
    'slui.exe 0x2a 0x8004FC12' to display the error text.

    Any help would be appreciated.

  • So after investing another 30 mins doing packet captures, removing and re-adding keys with slmgr etc.. I thought I'd try phone activation using "slui 4".  

    All worked fine and now activated.. Not sure why it wasn't working with online activation.

  • I have solve the same error with a simple two steps process:

    Start services.msc

    Restart Windows Update

    Restart Windows Installer
