The University of Tsukuba uses KMS (Key Management Service) license authentication method.
It does not require users to enter a product key when installing. Instead, it requires a periodic license authentication granted by the license authentication servers (KMS Host) in the university.
In order to prevent unauthorized license authentication, information such as the time of license activation, PC IP address, PC name, and terminal unique ID is recorded.

Check the status of License Authentication

Windows OS（Windows 10）

Click “start” and choose “Settings” > “Update & Security” and choose “Activation”. The activation status is displayed in the “Windows” section.

Office

Launch an Office application (Word, Excel, etc.) and click “Open Other 〇〇” from the menu on the left. Click “Account” or “Help” from the menu on the left side.
The current activation status is displayed in [Product Information].

Office for Mac

Click “Version Information” in the application menu (next to the apple mark). If the license item is “Volume License 201x”, it is an EES license.

If authentication fails

In normal conditions, the installer of our university should set KMS Host automatically, however, it could fail to register.

• Check1 ： Set the time zone to [UTC+09:00] (Osaka, Sapporo, Tokyo) in the time setting (including time zone) on your PC and make it set properly to the current time.
• Check 2 ：Connection settings (firewall) of your anti-virus software might be restricting connection with the server outside. If that is the case, please change your settings to allow connection. Set the firewall so that it can connect to TCP/1688 of the KMS Host (kms.cc.tsukuba.ac.jp).
