Upgraded to 9.5...should I uninstall 9.1?

I’ve just upgraded to WL 9.5.25 having previously had WL 9.1 and have noticed the file size in Windows Control Panel\Programs is only a third of the size of v 9.1.
Does the 9.5.25 upgrade depend on having 9.1 still installed in the computer or can I get rid of the previous version now?
Many thanks

You can get rid of 9.1

Thank you
