Can not open Libre Office 5.2.3.3 as it says I need permission and has a Fatal Error

The app can not be started Libre Office user installation could not be processed due to missing access rights. It says I should check C/users/app data/roaming/libre office /4 which I have and it is all there but what do I need to do to get it working again?

I have windows 10 on a Lenovo
