Checking you have 64-bit Excel

We recommend using Openbox on 64-bit Excel, as some users have experienced installation issues with 32-bit Excel on 64-bit Windows 10 or 11. 

Here is how to tell what version of Excel you are running:

  1. Open Excel
  2. Click “File” then “Account”
  3. Click the “?”/ “About Excel” icon

You should see a title ending with “64-bit”, as shown in the image below.

If you see “32-bit”, and are having issues installing Openbox, you may want to consider upgrading to 64-bit. Click here for advice from Microsoft on how to do this (it is free).
