Download and Install the Microsoft 365 Access Runtime

Use this method if you need to run Access applications on a PC that does not have the full Access software installed.

The Microsoft 365 Access Runtime is designed to be compatible with newer Click-to-Run Office installations, including Office 2021. Note that the installer may display 'Access Runtime 2016' during setup. This is a known Microsoft labeling issue and does not affect compatibility or functionality.

Frequently Asked Questions

Why does the Access Runtime installer say 2016 instead of 2021?

This is a known product-label issue from Microsoft. The underlying runtime technology is still fully compatible with Office 2021 and Microsoft 365, despite the older naming displayed in the setup wizard.

Can I install a 32-bit Access Runtime on a 64-bit Office installation?

No. The architecture (32-bit or 64-bit) of the Access Runtime must exactly match the architecture of your existing Microsoft Office installation. Mixing architectures will cause installation errors.

Does Office 2021 Home and Business include Microsoft Access?

No, Microsoft Access is not included in the Home and Business edition. You will need to upgrade to Office Professional 2021, use a Microsoft 365 subscription that includes Access, or deploy it separately.
