I tried installing animation nodes. Blender thought it installed it but it actually didn't (because it was the windows version and I was using Linux). I realized this when I ran into this problem. So I deleted that zip and downloaded the linux one. Now it shows up in the Add-ons folder when I select the .zip (as shown below) enter image description here

but when I click the checkbox to enable it, it gives me this error message: enter image description here

Thinking that Animation Nodes is already installed, even though the Windows version didn't show up in the Add-ons panel or anywhere on my hard drive. How can I get the proper version installed?

  • $\begingroup$ Go to the folder for the addons and delete the wrong version. The addons can be in two places C:\\program files\\Blender Foundation\ Blender\Version\scrips\addons\ and in C:\\Users\YourUserName\AppData\Roaming\Blender Foundation\Blender\version\scripts\addons. Delete form both places and Then start blender, and install the addon again from the User Preferences using "install from file" $\endgroup$

  • $\begingroup$ I'm using Linux so I don't have those locations on my hard drive. And when I do a search, I cannot find the old files. $\endgroup$ Jul 25, 2017 at 22:33
  • $\begingroup$ Then look for the places where the addons are. Depending on how they are installed on your system. should be something like /home/your user/.blender or something like that. it might be a hidden folder one starting with a period before the name. $\endgroup$

  • $\begingroup$ I already deleted all instances of the wrong version, as far as I can tell. Can I locate the user settings file and tell it that I don't have it installed anymore? $\endgroup$ Jul 25, 2017 at 23:02

    $\begingroup$ Type bpy.utils.script_paths("addons") into the python console. This will return a list of known addon locations. In my case ['/home/batfinger/src/BlenderGIT/kdev_build/bin/2.78/scripts/addons', '/home/batfinger/.config/blender/2.78/scripts/addons'] Remove addon from one of these locations. If the addon is in the blender contrib, as is animation nodes, I'd suggest removing the .config one. $\endgroup$

Click the disclosure triangle for the addon, you can find the path to the addon file in the info there.

  • $\begingroup$ Thanks! batFINGER's comment solved it. I appreciate the help. $\endgroup$ Jul 26, 2017 at 21:44

Both @cegaton's and batFINGER answered this correctly. I needed to go into the .config folder found in:


This helped blender to forget that it was installed.
