# 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

<details>

<summary>Which folder contains the most recent version?</summary>

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:

<img src="/files/5AN72JYPWLVBMPlcH0CV" alt="" data-size="original">

If you can only see a single version [contact us ](https://helpdesk.besmart.software/support/tickets/new)

</details>

4. Delete all files from that folder
5. Go to the folder of the ***previous*****&#x20;version** of the product. Example:

![](/files/Lb6i9TKFCeWlvc18GN3i)

6. Copy all content from that folder and move all the content to the folder of the most recent version of the product

![](/files/YuqGODEQq584Bj8yNPFr)

7. Relaunch Revit®, and you will be able to use the previous version of the product

### Updating to the newest version&#x20;
