GTX 960 4GB, windows 10 64-bit

blender 2.78a

I selected a wall created by the wallfactory addon which didn't work, so I tried it on a plane. Both got the same errors, even after I re-installed it:
/!\ Traceback (most recent call last):

File "C:\users\Sam\AppData\Roaming\Blender Foundation\Blender 2.78\scripts\addons    \add_curve_ivygen.py", line 583, in execute IVY.grow(ob)

File "C:\users\Sam\AppData\Roaming\Blender Foundation\Blender 2.78\scripts\addons\add_curve_ivygen.py", line 332, in grow self.maxAdhesionDistance
File "C:\users\Sam\AppData\Roaming\Blender Foundation\Blender 2.78\scripts\addons\add_curve_ivygen.py", line 408 in adhesion adhesion_vector = ob.matrix_world* nearest result- [x] - loc
TypeError: Matrix subtraction: (Matrix - vector) invalid type for this operation

location :-1

I'm not very familiar with python, but I think that the error report refers to a fault in the coding (line ...)

I have tried every single mesh generator I have (includes the extra meshes: https://wiki.blender.org/index.php/Extensions:2.6/Py/Scripts/Add_Mesh/Add_Extra).

Create mesh
Add Ivy curve
Get an error
My version of the .py script:
add_curve_ivygen.py

Thanks for the report but this is now fixed in daily builds, it's worth checking these before reporting.

I'm not very known with this particular site, so where can I find the daily builds?

I've installed the build now, but I seem to get exactly the same error. I tried using the 32-bit build (I'm using windows 10 64-bit) and the 2.80 build, which both failed.

It work fine for e with the latest build.
This is more a support question.
Please open a thread at Blender Artists, may me or other user can help.

@samtt
From the path of the add-on error you're using a script located in the Blender config folder. Be sure that you have enabled only the add-on shipped with Blender (i.e from the unpacked directory and not from the config path on the C drive).
