This page explains how to install the OneMore add-in for the desktop edition of OneNote.


Please note that I cannot support Microsoft Office Insider or Beta builds.


Install OneMore as an Administrator

The OneMore installer requires admin rights to complete configuration and update the Windows Registry. If your account has admin rights then follow these steps.


  1. Close OneNote if it is currently running (See below if you need to install OneNote)


  1. Download the latest installer from here
    • Download the proper installer for your version of Windows. This has nothing to do with the architecture of Office; the installer simply needs to match the architecture of Window.
    • Use the x64 installer when running on a 64-bit Windows machine. This works with both 32-bit and 64-bit Office.
    • Use the x86 installer only if you are running on a 32-bit Windows machine.


  1. Right-click the downloaded installer .msi and choose Properties, then tick the Unblock box and click OK


  1. Double click the .msi to Run the installer
    • If you're currently logged in as a user with admin rights and this is the account with which you will use OneMore then you will be able to start OneNote immediately.
    • Other users on the system will experience a slight delay the first time they log in after OneMore is installed while settings are applied to their accounts. This only occurs once.
    • If you're currently logged in as a user without admin rights, you can install OneMore if you have the user name and password of an account with admin rights. See below for further instructions.


Install OneMore as a Normal User

If you have the user name and password of an account with admin rights, you can run the OneMore installer from your current account using this command entered from a console window:


runas /user:<username> "msiexec.exe /i <path-to-installer>"


where <username> is the user name of an account with admin rights and <path-to-installer> is the full path to the OneMore installer .msi file


You will be prompted for the password of the admin user. The installation will continue.


You must sign out and then sign in again before you will see OneMore in the OneNote ribbon.


Upgrade OneMore

The OneMore installer is built such that it can be installed on top of an older version and will effectively perform an upgrade. This is the preferred method and can be done in one of two ways:


  1. Open the OneMore About dialog and click Check for updates. If there is a new version available, you will be given the option of upgrading. OneNote will be shut down to perform the upgrade.


  1. Or, download the OneMore installer and run it. There is no need to uninstall the previous version; the new installer will simply overwrite the old files and upgrade OneMore. Note that when you download the installer, you will need to unblock it by opening its Properties dialog and clicking the Unblock checkbox. Follow the instructions above.
