Device & OS
not provided
Scenario
A vulnerability scanner or system audit detects 32-bit Office remnants on a machine that is supposed to only run the 64-bit version of Office 2016.
Observed behavior
Microsoft does not provide a supported method for isolating and removing only 32-bit remnants while leaving the 64-bit installation in place, causing mixed components to remain.
Before you start

Ensure you have your Microsoft Office 2016 product key or your Microsoft account login details ready, as you will need to perform a complete reinstallation of the software.

Solution 1Recommended

Perform a Clean Uninstall and Reinstall

Since Microsoft cannot isolate and remove only the 32-bit remnants, the most reliable method is to completely remove all Office components and reinstall the 64-bit version.

Mixed architecture installations (both 32-bit and 64-bit files) happen when an older installation isn't fully removed before upgrading. The official Microsoft Support and Recovery Assistant is required to wipe all existing traces of Office.

1
Verify current installation bitness

Open an Office application like Word. Go to File > Account > About Word to verify your current version and architecture.

2
Download the Uninstall Tool

Navigate to the official Microsoft Support website and download the Office uninstall tool (Support and Recovery Assistant).

3
Run the tool

Launch the downloaded tool, select Option 2 for Office 2016, and follow the on-screen prompts to completely remove all Office components from your PC.

4
Restart your computer

Once the uninstall tool finishes its process, restart your computer to ensure all registry keys and temporary files are cleared.

5
Reinstall 64-bit Office 2016

Log into your Microsoft Account, navigate to your subscriptions or purchases, download the 64-bit installer, and reinstall Office.

Installation Tip: By default, some Microsoft installers may still default to 32-bit. Be sure to manually select 'Other install options' and choose '64-bit' before downloading the setup file.

Frequently Asked Questions

Why does my PC show that I have both 32-bit and 64-bit Office installed?

This typically occurs if you previously installed a 32-bit version of Office and upgraded to 64-bit without completely uninstalling the old version. It can also happen if you installed standalone 32-bit applications like Microsoft Visio or Project alongside your 64-bit Office suite.

Can I manually delete 32-bit Office files from the Program Files (x86) folder?

It is highly discouraged to manually delete files from the installation folder. Doing so can corrupt the Windows Registry and cause your remaining 64-bit Office applications to crash. Always use the official Microsoft uninstall tool.

Will uninstalling Office 2016 delete my Word and Excel documents?

No, uninstalling Microsoft Office only removes the software applications. Your personal documents, spreadsheets, and presentations saved on your hard drive, desktop, or OneDrive will remain entirely untouched.

How do I check if my installed Office 2016 is 32-bit or 64-bit?

Open any Office application, such as Word or Excel. Click on File, select Account, and then click the 'About' button. The exact bitness (32-bit or 64-bit) will be listed at the top of the dialog box that appears.
