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:
- Open Excel
- Click “File” then “Account”
- 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).
