How To Run Excel In 32 Bit Mode

If you’re running a 64-bit version of Microsoft Excel on your computer, there might be situations where you’ll need to switch to the 32-bit version. Some add-ins or extensions might not be compatible with the 64-bit version, or maybe you’re working with large data sets that require more memory allocation, which is something the 32-bit version excels in. This guide will walk you through the process of running Excel in 32-bit mode.

Uninstalling the 64-bit version

Before you can install the 32-bit version of Excel, you’ll first need to uninstall the 64-bit version. Here’s how:

  1. Open the Control Panel on your computer.
  2. Select Programs and then Programs and Features.
  3. From the list of installed programs, find your Office installation, click on it, and then click the Uninstall button.

Installing the 32-bit version

Once you’ve uninstalled the 64-bit version of Excel, you can now install the 32-bit version. Follow these steps:

  1. Go to the Office 365 website and log in with your account.
  2. Click on the Install Office button.
  3. In the following screen, click on Other options.
  4. Check the box that says “Install the 32-bit version”. If you can’t find this option, it might be labelled as “Advanced” instead.
  5. Click on the Install button to start the installation process.

Confirming the installation

After you’ve installed the 32-bit version of Excel, you’ll want to confirm that it was installed successfully. To do this, open Excel and then go to File > Account > About Excel. In the information window that opens, you should see “32-bit” somewhere in the first line of text.


Switching from the 64-bit version of Excel to the 32-bit version might seem a bit intimidating at first, but as long as you follow the steps above, it’s actually quite straightforward. Remember, you can always switch back to the 64-bit version if you need to in the future. Happy spreadsheeting!
