# How to revert to a previous version of a tool?
### Reverting to an old version
If you [want to revert](#user-content-fn-1)[^1] to the previous version of a product, follow these steps:
1. Close Revit®
2. Go to: Users\\%username%\AppData\Roaming\TOOLS 4 BIM\\\*Revit® version\*\\**\*Product\***
3. Find and enter the folder of the most recent version of the product
Which folder contains the most recent version?
The 3rd & 4th digits in the folder name indicate the product version: the bigger the number, the newer the version. So, the most recent version of the product is in the folder with the biggest number formed by the 3rd & 4th digits in its folder name. (The first 2 digits of the folder name indicate the Revit year/version.) Example:
If you can only see a single version [contact us ](https://helpdesk.besmart.software/support/tickets/new)
4. Delete all files from that folder
5. Go to the folder of the ***previous***** version** of the product. Example:
6. Copy all content from that folder and move all the content to the folder of the most recent version of the product
7. Relaunch Revit®, and you will be able to use the previous version of the product
### Updating to the newest version
When you are ready to update a product to the newest version, follow these steps:
1. Close Revit®
2. Go to the ARKANCE Dock: \Users\\%username%\AppData\Roaming\TOOLS 4 BIM\\\*Revit version\*\\**\*Product\***
3. Delete all files that are in the **\*Product\*** folder
4. Launch Revit® > open any project > open the ARKANCE Dock.

## 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.besmart.software/getting-started/faq/how-to-revert-to-a-previous-version-of-a-tool.md?ask=&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.
