I have "xampp-win32-1.8.3-5-VC11-installer" and it requires a new folder because I already have an older version (Control Panel v3.2.1 07052013) in C:\xampp. What should I do?

PS. I still end up on the german page when selecting community (https://community.apachefriends.org/f/)

This shows, that upgrading is somewhat laborious:
