# WinFsp 显示“已安装”错误

“WinFsp 已安装”或“已安装较新版本”错误，可能是由于先前安装 WinFsp 时残留的文件、注册表项，或版本冲突所致。您可以通过安装 WinFsp 2.1（版本 2.1.25156）来解决此问题，这也是 Shade 安装程序使用的同一版本： [下载 WinFsp 2.1.25156](https://storage.googleapis.com/v2-public.shade.inc/libraries/winfsp/winfsp-2.1.25156.msi).

此版本通过正确清理您设备上的旧版 WinFSP 来解决此问题。

# 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://academy.shade.inc/help-center/help-center-zh/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.
