    I installed office 2010 and tried activating using Toolkit 2.5.2 that was provided together with the downloads.

    Installed AutoKMS. Clicked on Activate and get this error:

    Failed to start KMS Emulator!
    KMS Port may be in use.

    ERROR TEXT: The Software Licensing Service reported that the product could not be activated. No Key Management Service (KMS) could be contacted. Please see the Application Event Log for additional information.

    Here are some of the thing I have tried:

    - disabled antivirus
    - change to TAP adapater
    - uninstall AutoKMS - reinstall AutoKMS
    - reboot PC

    Sorry, I am new to this. I prefer 2010. But if this is too old, don't mind getting a version that works. Thanks.

    Thanks for the prompt reply.

    Here are the results:
    1) latest version of Microsoft Toolkit - doesn't work. Same issue. Doesn't with port 1686 as well.
    2) KMS_VL_ALL - works. Now I have 180 days activation.

    Appreciate the help.
