How to Fix 32-Bit Access Runtime Installation Failure with 64-Bit Office
Question details
The user is unable to install a 32-bit Access Runtime required by a third-party application because it conflicts with an existing 64-bit Microsoft Office Standard 2019 installation.
- Product
- Microsoft Office 2019
- Device & OS
- not provided
- Scenario
- Attempting to install a 32-bit database provider for a software like AquaChem on a computer that already has 64-bit Office installed.
- Observed behavior
- The installation of the 32-bit Access Runtime fails and is blocked by the system because matching 32-bit and 64-bit Office components cannot be installed side by side for the same version.
Verify your current Microsoft Office architecture by opening any Office app, navigating to File then Account, and clicking About to confirm you are running the 64-bit version.
Install a Compatible Older Version of Access Runtime
Bypass the version conflict by installing an older 32-bit Access Runtime release alongside your newer 64-bit Office installation.
Microsoft Windows prevents the installation of 32-bit and 64-bit components from the same Office release year (such as 2019). However, you can often install a 32-bit runtime from an earlier generation, provided your third-party application supports it.
Navigate to the official Microsoft Download Center and search for Microsoft Access 2013 Runtime or 2016 Runtime.
Choose the 32-bit installer option, typically labeled as x86, and download the file to your computer.
Double-click the downloaded setup file and follow the on-screen prompts to install the runtime.
Restart your computer and open your third-party software (e.g., AquaChem) to verify it can now detect the 32-bit database provider.
Uninstall 64-Bit Office and Install the 32-Bit Version
Standardize your entire system to a 32-bit architecture to ensure seamless compatibility with the required Access Runtime.
Run the 32-Bit Environment in a Virtual Machine
Isolate the 32-bit database provider and its parent application in a virtualized environment, leaving your host machine's 64-bit Office untouched.

Frequently Asked Questions
Why can I not install 32-bit and 64-bit Office programs on the same computer?
The Windows installer relies on shared registry keys and core components for Microsoft Office. Mixing 32-bit and 64-bit versions of the same release year causes severe registry conflicts, so the installer actively blocks it to prevent software corruption and system instability.
How do I check if my Microsoft Office is 32-bit or 64-bit?
Open any Office application like Word or Excel. Click on File in the top left corner, navigate to Account, and click the About Word or About Excel button. A dialog box will appear displaying the exact version number and its architecture (32-bit or 64-bit).
Does WPS Office include a database software like Microsoft Access?
WPS Office includes Writer, Spreadsheets, and Presentation tools which serve as powerful alternatives to Word, Excel, and PowerPoint. It does not include a direct equivalent to Microsoft Access, meaning you will still need the Access Runtime for specialized third-party database tools.
