Compared to earlier versions, it has three different versions and these are Community, Professional and Enterprise. We can download Visual Studio 2017 from the Visual Studio official site. At that point of time, C# didn't exist and Visual Basic, Visual C++ etc. The first version of Visual Studio IDE was released on March 19, 1997, which was Visual Studio 97. Visual Studio 2017 is the most awaited software from Microsoft. I'll keep this post updated if I find any more cases with fixes.Recently, Microsoft launched Visual Studio 2017 on the 20 th Anniversary of Visual Studio IDE. Thought I'd put this out there, as the other fix is to reinstall Unity, which can take a whole lot longer. It also makes me wonder why relative paths still aren't a thing in some Windows programs in 2017. It fixed mine when I ran into that snag after moving the installation. Now, you can open unity, and start developing again no issues. The second thing you need to do is to navigate to C:\ProgramData\Unity (you'll need "Show hidden files" turned on) and delete the file "index-local.xml" (This folder also where the license file is located, so be careful going into this folder!) Right-click, modify and type the new install directory path into Value Data. So, to the fixes: The first involves the registry Win+R, type regedit to open the registry, navigate to the following key "HKEY_CURRENT_USER\Software\Unity Technologies\Installer\Unity" (or just find the path with Ctrl+F) and in there is an entry in there called "Location 圆4" I got this after moving my Unity install off the C: drive onto my D: drive so Windows 10 could update properly, (Unity was taking 3GB of space) and through trial and error (and some hints from some googling) I found how to reset all the paths after moving. Easier said than done however, as attempting to open a project may result in "nonexistent playback engines" and a few other errors/warnings in the console. The first step is actually moving the entire install folder to the new location.

(This guide assumes you're using Windows 圆4) With that out of the way, I'm putting this here for those who for some reason need to move their unity installation to a different drive on the same PC. Hello guys, not sure where to actually put this, so if someone can move it, that would be great. These instructions may still be useful for those who decide for whatever reason to install Unity separately outside of using the Hub, especially older Unity versions made before the existence of Hub! 2021 Update: With the existence of Unity Hub, this method of moving installations is irrelevant.
