How can I uninstall an Add-on?

I asked a question yesterday about how to bring filled polylines in from AutoCAD without them coming in as joined filled shapes. I was directed to a download site to get a new dxf importer. I installed it as directed but now I have two dxf converters installed in Blender and they conflict so that I can't bring dxf files in at all. How can I uninstall the old one?

I suppose I could uninstall Blender and then reinstall it, but then I would have the same question. Can I bring in polylines from AutoCAD without them linking to each other and creating a maze of linked filled shapes?

• The old one looks like it is disabled, did you save user settings? – VRM Mar 10 '15 at 19:32

You need to delete the .py file. To do this on windows, go to C:\Program Files\Blender Foundation\Blender\[version]\scripts, and find the scripts location. Then delete the files.

Here in the screenshot of the user preferences (Which can be accessed via Ctrl-Alt-U>Scripts) you can see the location of the script files that need to be removed.

• NoviceInDisguise, no I did not save my user settings. I followed the directions given by GiantCowFilms and was able to remove the newly installed DXF importer. At least it appears to be the one deleted when I removed the init.py file. I then went to the Addons menu in Blender and saw that there was only one "Import-Export: Export Autocad DXF Format (.dxf)" option in the list. It looks to be the one I used initially that had the running man icon and the explanation mark sign that indicated "Under Construction". It is version 8.1.3. Can and should I replace it? – Randy Van Nostrand Mar 11 '15 at 14:07
• I would get rid of all of them then install the one you want – GiantCowFilms Mar 11 '15 at 14:35
