How to Fix InfoPath 2013 Crashing After Installing Office 2019

Product: Microsoft InfoPath 2013, Office 2019
Device & OS: not provided
Scenario: Opening InfoPath 2013 after installing or updating Microsoft Office 2019 components.
Observed behavior: InfoPath 2013 closes unexpectedly after the First Things window, generating an APPCRASH error involving INFOPATH.EXE, mso.dll, and exception code c0000005.

Before you start

Before applying any registry modifications, ensure you create a complete backup of your Windows Registry and close all running Microsoft Office applications to prevent data loss.

Solution 1Recommended

Apply the Official Registry Workaround

Modify the Windows Registry to resolve the component compatibility conflict between InfoPath 2013 and Office 2019.

This compatibility conflict often arises because InfoPath 2013 attempts to access newer shared Office components (like mso.dll) installed by Office 2019, resulting in an access violation (c0000005). Microsoft has documented specific registry adjustments to force InfoPath to run correctly in this mixed environment.

Open the Registry Editor

Press the Windows Key + R on your keyboard, type 'regedit' into the Run dialog box, and press Enter. Click 'Yes' if prompted by User Account Control.

Navigate to the Office Registry Key

Locate the specific registry path detailed in Microsoft's official support document for the InfoPath 2013 and Office 2019 workaround (typically found under HKEY_CURRENT_USER\Software\Microsoft\Office).

Apply the Required Value Changes

Right-click in the right pane, select New, and choose the appropriate value type (usually DWORD). Name it and set its value data exactly as instructed by Microsoft's workaround.

Restart Your Computer

Close the Registry Editor and restart your computer to apply the changes, then launch InfoPath 2013 to verify stability.

Registry Caution: Incorrectly modifying the registry can cause severe system damage. Always double-check your entries against official Microsoft documentation and maintain a recent backup.

Solution 2

Install the Latest Office and InfoPath Updates

Update both InfoPath 2013 and Office 2019 to the latest versions to patch known mso.dll conflicts and bugs.
