How to Fix Microsoft Access Runtime Opening Instead of Full Access

Product: Microsoft Access
Device & OS: not provided
Scenario: Opening an Access database file (.accdb) from a local computer.
Observed behavior: The system opens Microsoft Access Runtime and prompts for an Access file or database, preventing the user from utilizing the full database design and editing features.

Before you start

Verify that you have an active Microsoft 365 subscription or a standalone license for the full version of Microsoft Access installed on your PC.

Solution 1Recommended

Uninstall Access Runtime and Set Default Application

If both versions are installed, removing the Runtime version resolves the conflict and allows the full application to open by default.

Third-party applications sometimes install Access Runtime automatically. If you already have the full version of Microsoft Access, the Runtime version is unnecessary and can cause file association conflicts.

Open Programs and Features

Open the Windows Control Panel and navigate to 'Programs' > 'Programs and Features'.

Uninstall Access Runtime

Scroll through the list of installed programs to find 'Microsoft Access Runtime'. Right-click it, select 'Uninstall', and then restart your computer.

Set default application

Locate an .accdb file on your computer, right-click it, and select 'Open with'. Choose the full Microsoft Access application and ensure the 'Always use this app to open .accdb files' box is checked.

File Associations Updated: Setting the default application ensures Windows always uses the full Access program to open your database files in the future.

Solution 2

Repair Your Microsoft 365 Installation

Use the built-in Microsoft 365 repair tool to fix file associations and corrupted application settings.

Frequently Asked Questions

What is the difference between Access Runtime and full Access?

Microsoft Access Runtime allows users to run existing database applications but lacks the design-time tools needed to create, modify, or customize the database structure. The full version includes all design, development, and editing features.

Why was Access Runtime installed on my computer?

Access Runtime is often installed automatically as a prerequisite by third-party software applications. These programs use an Access database on the backend but deploy the free Runtime version so users aren't forced to purchase the full Office suite.

Will uninstalling Microsoft Access Runtime delete my database files?

No. Uninstalling the Runtime environment only removes the software used to open the files. Your actual database files (.accdb or .mdb) are stored independently on your hard drive and will remain completely intact.
