# WinFsp shows an "already installed" error

The "WinFsp is already installed" or "newer version installed" errors were likely caused by residual files, registry entries, or a versioning conflict from a previous WinFsp installation. You can resolve this issue by installing WinFsp 2.1 (version 2.1.25156), the same version that the Shade installer uses: [download WinFsp 2.1.25156](https://storage.googleapis.com/v2-public.shade.inc/libraries/winfsp/winfsp-2.1.25156.msi).

This version resolves the issue by properly cleaning up older versions of WinFSP on your machine.

## 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://academy.shade.inc/help-center/shadefs-faq/winfsp-is-showing-an-already-installed-error.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.
