This post will simply be a record of what I have done to run Unity using wine on Linux. This may not be the best approach, and the process you need to go through might be different than what I have done.
What you will need:
The Unity installer. I installed version 4.2.1.
Wine. This is best obtained from your disto’s repositories, unless you feel comfortable compiling wine yourself. (Don’t. Just don’t.) I used Wine 1.7.1.
A small amount of skill with a command line interface. Not a lot, because I’ll show you the commands I ran during the installation of Unity.
To begin, create a new 32bit wine prefix:
The prefix has to be 32bit for Unity to run correctly. Next, get winetricks. Right-click that link and save it somewhere. Then run:
You might also need to install other fonts. If Unity doesn’t work at the end of this, try running winetricks and selecting “install fonts” after selecting the current prefix. Don’t install “all-fonts”, but instead choose fonts individually.
I’ve heard that creating the folder “$WINEPREFIX/drive_c/users/$USER/AppData/LocalLow” in your wine prefix will allow you to create new projects, but it didn’t work for me. Try it if you want.
Next is the fun part: tricking Unity into thinking you have a registered Windows install. Run your wine regedit (Windows registry editor). one way to do this is by using winetricks:
Navigate to “HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\” and create a new string value. Call it “ProductId”. It doesn’t even have to have an actual value, it just has to exist.
Now, finally, we can install Unity. In my case, this is:
Install it wherever you want.
One last thing: I couldn’t get Unity to actually create a new project, so here is my workaround: create a new folder wherever you want a project to be saved. In Unity’s initial dialog, open a project folder, navigate, to the folder you just created, and tell Unity to open that. it creates the necessary asset folders and project settings.
That’s it. As I said before, this might not work for you if you are using a different version of Wine, or a different version of Unity, or for any other reason. Still, I hope this post helps you get started installing Unity!
