# Visual C++ Redistributable Requirement

## Troubleshooting: Visual C++ Redistributable Requirement

When running a PHP application compiled with ExeOutput for PHP, you or your users might encounter an error message indicating that a specific version of the Visual C++ Redistributable is missing.

This error occurs because the PHP runtime and the [CEF engine](cef-engine) rely on the Visual C++ Redistributable to function correctly. Without the appropriate runtime, your application cannot execute.

### Required Versions

The required version of the Visual C++ Redistributable depends on the components you use in your application.

- **For applications using CEF version 139 or later:** A minimum of **Visual C++ 2022 Redistributable** is now required. Higher versions are backward compatible.
- **For older versions or other components:** The **Visual C++ Redistributable for Visual Studio 2015-2019** might be required.

ExeOutput for PHP 2025 and later use CEF 139+.

### Download Links

You can find the necessary installers in the `Redist` subfolder of the ExeOutput for PHP installation directory. The installers are also available for download from the official Microsoft website:

- [Download the latest supported Visual C++ Redistributable](https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170)

Ensure that you download the **x86** version for 32-bit applications created with ExeOutput for PHP.

### Including the Runtime in Your Installer

To provide a seamless installation experience for your users, you can bundle the Visual C++ Redistributable runtime with your application's installer (for example, one created with **Paquet Builder**). This ensures the necessary runtime components are installed automatically with your application, eliminating the need for users to install them manually.

For detailed instructions, please refer to our [Creating an Installer with Paquet Builder](distributingpub) guide.
