Wath do I need to do to upgrade panda 3d to a newer version?

Im on windows and I have panda 3d 1.6.2 installed and I want to upgrade to the latest (1.7.1).

Do I need to uninstall, delete the panda 1.6.2 folder in C:/ or can I have both versions installed?

Welcome to the forums!

You can technically have two versions installed at the same time on Windows, but it is not recommended. I advise uninstalling 1.6.2 (which will remove the directory) and then installing 1.7.1.
