# How To Fix Access Violation error (Windows)

## What is this error? 

This is a rare error message that will show up in your "Experts" tab on mt5. This error affects a very small amount of users (usually only Windows 11 users). Typically this error happens because of one or more of these reasons: 

* You are using a special version of MT5 not the official one
* Your Windows is not fully up to date 
* Your latest version of MT5 is bugged and you need to rollback to a previous version 

### Make sure your windows is updated to the most recent version: 

If you are on Windows 11 that is not version 22621 and above you will need to update your Windows. Please make sure your Windows version is up to date.

### Make sure you are using the official MT5 and not a special version:

The indicator can have issues when using a special MT5 version from a 3rd party. We recommend using the official version which you can download here <https://www.metatrader5.com/en/download>

### Rollback your MT5 version:

If you are on the latest version of Windows and you are using the official version of MT5 and you are still having this error, below is a walkthrough on how fix this.&#x20;
