Incomplete or corrupted previous installationsRegistry conflictsInsufficient permissionsLeftover installation files from earlier attempts
These issues prevent the system from properly recognizing or reinstalling the runtime. We’ve outlined a set of proven methods to resolve this installation conflict below.
1. Run WebView2 Runtime Installer as Administrator
Running the WebView2 Runtime installer with administrative privileges ensures it can access and modify necessary system files and registry entries. Standard user accounts may lack the permissions needed to complete the installation properly. To avoid issues like file write errors or configuration failures, always run the installer as an administrator.
2. Perform a Clean Reinstallation of WebView2 Runtime
A clean reinstallation of WebView2 Runtime ensures that any corrupted files or incorrect registry entries left behind from previous installations are removed. These remnants can block new installations by falsely indicating that WebView2 Runtime is already installed. By fully removing all existing components before reinstalling, you eliminate potential conflicts and allow the runtime to install properly.
3. Configure the Registry Entries
If the issue persists, it may originate from incorrect or missing registry entries related to WebView2. Adjusting these entries can help the system re-recognize WebView2’s installation state and remove invalid registry flags that may block reinstallation. Especially if WebView2 is required for EAC’s UI components or backend communication.
4. Repair the WebView2 Runtime Installation
Repairing the WebView2 Runtime can help resolve conflicts or errors preventing proper functionality. This method is especially useful if previous fixes haven’t worked and the issue persists during installation attempts. If you’ve followed all the methods outlined above, the issue should be resolved. However, if the problem persists despite applying all solutions, consider reaching out to Microsoft Support for further assistance tailored to your specific case.
