# Resetting Installation

If you broke your installation of OMORI (meaning it doesn't work properly or at all), then you can fix your installation using Steam.

**This might override (delete) mod files, so make sure you back up files you want to keep.**

Save files should not be affected, but they might become unusable if they require a specific mod.

Here's how to fix your installation:

1. Open Steam
2. Right-click OMORI and choose *Properties*
3. On the tabs on the left, click *Local files*
4. Click *Verify integrity of game files…* This will make Steam check the files and cue an update to download fresh files from it's server if needed.

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://omori-modding.gitbook.io/wiki/getting-started/decryption-and-playtest-generation/resetting-installation.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
