File Access Error on Installation

I am trying to upgrade my Unreal Engine 4 from version 4.22 to 4.25, but I get the following error:

Install Failed

A file access error has occurred. Please check your running processes.

Error Code: IS-MF01-1392-1392

Can anyone help me out?

Can you close all Unreal applications from the task manager and verify if you have enough disk space for this?
