I need to downgrade from git version 2.14.2 to version 2.8.1. I've tried downloading the 2.8.1 files from this link, but I'm not actually sure what to do with them to install. There also seems to be conflicting answers in my google search as to whether you need to uninstall the current git version. Please let me know what I should do in order to downgrade git versions. I am using Windows 10.
