LO wont start

Hi all

I have used LO for many years on my desktop with no trouble, my son has given me his Dell lap top and I have installed LO but when i try to open the app it stop half way and the following message comes up

The application cannot be started.
[context=“user”] caught unexpected
com.sun.start.deployment.DeloymentException: Extension Manager:
failed to read data entry in configuration backed db:
file:///C:/User/Gareth/AppData/Roaming/LibreOffice/4/4user/uno_pac.
kages/cache/registry/com.sun.comp.deployment.configuration.PackageRegisrtyBacked/backenddb.xml

How can I fix this issue?

cheers

It looks like one of LibreOffice extensions is broken or incompatible with the current version of LO. Try resetting your user profile.
