# Microsoft Edge WebView2 runtime installation troubleshooting

Microsoft Edge WebView2 Runtime installation failure for Remote Desktop Manager is fixed by deleting a specific registry key before reinstalling.

When installing the Microsoft Edge WebView2 Runtime for Remote Desktop Manager, you may get the following error message:

**Installation failed. The Microsoft Edge WebView2 Runtime is already installed for the system.**

### Solution

Force the reinstallation of the program by deleting a registry key:

1. Open the Windows Registry Editor. To do so, press the <kbd>Windows</kbd>+<kbd>R</kbd> keys to open the Windows ***Run*** dialog.
2. In the dialog box, enter "regedit" in the field then click ***OK*** (or press <kbd>Enter</kbd>).
3. Copy the following path: **`HKLM\SOFTWARE\WOW6432Node\Microsoft\EdgeUpdate\Clients\{F3017226-FE2A-4295-8BDF-00C3A9A7E4C5}`**
4. In the Registry Editor, press the <kbd>Alt</kbd>+<kbd>D</kbd> keys and paste the previously copied path. Press <kbd>Enter</kbd>.
5. Right-click the ***{F3017226-FE2A-4295-8BDF-00C3A9A7E4C5}*** key and select ***Export***.
6. Save the registry key file in a location you will remember, for example in **C:\Program Files (x86)\Microsoft\EdgeWebView2**.
7. Right-click the key in the Registry Editor and select ***Delete***.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.devolutions.net/rdm/knowledge-base/troubleshooting-articles/microsoft-edge-webview2-runtime-installation-troubleshooting.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
