I downloaded and installed Unity 5 from the downloader, and I later found out that it downloaded a 64bits version, when my old Unity 4 was 32bits (my machine is 64bits, that’s not the problem). I went in Window’s control panel and tried to find Unity 4, but there was only one version of Unity and its web player: 5. However, Unity 4’s files are still in Programs Files(x86). How can I uninstall Unity 4? Do I simply use the uninstall exe or I need to erase many files manually?
There should actually be an uninstall option in the Start Menu entry for Unity 4, that’s how I got rid of it.
