# Does fspy add-on work in blender 2.81?

I have tried installing fspy in blender 2.81, however it says it is 'installed' (as can be seen in attached image) but then doesn't appear in add-ons list, and hence cannot be enabled.

You installed the wrong file; you need to install fSpy-Blender-1.0.3.zip  (or newer) from the Releases page.
The file you're using, fspy-Blender-master.zip is likely the source code and doesn't work as addon.
