Can You Install 32-Bit and 64-Bit Excel Together on Windows?
Question details
The user wants to know if it is possible to have both 32-bit and 64-bit versions of Microsoft Excel installed and running on the same computer concurrently.
- Product
- Microsoft Excel
- Device & OS
- Windows
- Scenario
- Planning an Office installation or attempting to resolve compatibility issues with legacy add-ins and macros that require a specific system architecture.
- Observed behavior
- Microsoft Office prevents the installation of a different architecture if one is already present, meaning the 32-bit and 64-bit versions cannot coexist on the same system.
Verify your system requirements and determine if your specific legacy add-ins or ActiveX controls strictly require a 32-bit architecture before uninstalling your current Office suite.
Uninstall and Switch Your Office Architecture
Since Windows does not allow 32-bit and 64-bit Office installations to coexist, you must completely uninstall your current version before installing the required architecture.
Microsoft Office restricts installations to a single architecture to prevent registry conflicts and shared component errors. A 64-bit version of Windows can run either 32-bit or 64-bit Office, but not both simultaneously.
If you need 32-bit Excel for legacy COM add-ins, you must remove the 64-bit version entirely. Keep in mind that standard VBA macros usually work perfectly on 64-bit systems, so only downgrade if a specific plugin demands it.
Open the Windows Start menu, navigate to Settings > Apps > Installed apps, locate your Microsoft Office or Microsoft 365 installation, and click 'Uninstall'.
Go to the official Microsoft Office website and sign in with the account associated with your Office or Microsoft 365 license.
Click on 'Install Office', choose 'Other options', and select the specific version (32-bit or 64-bit) you need from the dropdown menu.
Download the setup file, double-click to run it, and follow the on-screen instructions to complete the installation of the chosen Excel architecture.

Frequently Asked Questions
Why does Microsoft prevent installing both 32-bit and 64-bit Office?
Installing both architectures simultaneously would cause severe registry conflicts and shared component errors. Windows relies on a single set of shared Office libraries to run applications like Word and Excel smoothly.
Do I need 32-bit Excel to run normal VBA macros?
Generally, no. Standard VBA macros work perfectly on 64-bit Excel. You typically only need the 32-bit version if your workbook relies on specific 32-bit legacy add-ins, older ActiveX controls, or specific 32-bit DLL files.
Will I lose my Excel files if I uninstall 64-bit Office to install 32-bit?
No, uninstalling the Microsoft Office suite only removes the application files. Your personal Excel workbooks (.xlsx) and documents will remain safely stored on your hard drive.
How do I check if my installed Excel is 32-bit or 64-bit?
Open Excel, click on 'File', select 'Account' (or 'Help' in older versions), and then click 'About Excel'. The top of the pop-up window will display whether you are currently using the 32-bit or 64-bit version.
