    I've just installed Unity 5 and realized that it didn't remove Unity 4.6. Is it suppose to still be there after Unity 5 has been installed? Do I need to manually remove it?

    You should keep it, in case you need it for something.

    I will note here that 4.6 works perfectly as if nothing was installed over it if you install unity 5, so I recommend keeping it around for if a project upgrade to Unity 5 goes horribly wrong... :D

    Also noting: this only seems to happen on x64 based systems. (This is due to Windows splitting program files into two groups)

    I had Unity 4 installed so that I could go through some online tutorials. I now have Unity 5 installed for the same purpose and hopefully to actually do some creating. My Unity 4 installation doesn't have any saved projects or use for me any more, but it doesn't appear in the list of programs in Windows' Add/Remove Programs. Unity 5.3.1 does appear, but nothing for Unity 4.6.1. I see that Unity 4 is still taking up 5GB of hard drive space in my Program Files (x86) folder, so I would like to remove it, but I don't want to just delete it and leave behind registry clutter.

    Has anyone successfully - and cleanly - removed Unity 4 after installing 5?

    Thanks!

    I did by removing 4.x first. ;) Ah well, things do go wrong from time to time. :)

    Installing 5 over 4 seems to have some other issues; I found last night that Unity won't open Visual Studio 2015 to edit scripts even though I have it selected as the external script editor. I see a progress bar that says it's opening Visual Studio and then MonoDevelop opens the script with an error message saying it's having a problem loading an object of an unknown type.

    Searching the issue tracker I see that this is a problem that is marked solved in an update to Unity 4, but for me it's still happening with Unity 5.

    I was hoping to spend time learning to use Unity and not learning how to work around its installation bugs. :rolleyes:

    For what it's worth, in case someone else finds this thread who is having the same problem:

    I was able to fix the problem with Unity opening MonoDevelop instead of VS2015 by opening Visual Studio 2015 on its own and updating the File Associations to include .CS files.
