Microsoft 365 Apps can now be installed on Mass General Brigham servers. Follow the instruction for Other Windows Computers above to install the apps.

Once installation is complete, you will have to add the “SharedComputerLicensing” registry key. This setting allows any licensed user to run Microsoft 365 Apps on the server. See this Microsoft article for more information about shared computer activation.

There are two ways to add the key to the server:

  • Click here to download the .reg file. From your Downloads folder, double-click the .reg file to create the registry key.
  • Or, use the Registry Editor to navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\ClickToRun\Configuration > Add the SharedComputerLicensing key > and set value to 1



After Office has been installed, it needs to be activated. When prompted, enter your primary Mass General Brigham email address and password to activate Office.
