I was trying to install the add-on Blam Master and for any reason was not showing up, and didn't show any action confirming the installation. I try to run it again an this error popped out:

Multiple addons using the same name found!
likely a problem with the script search path.
(see console details)

Looking at the console nothing shows up... Also, I tried to search for the duplicate file in the Program Files folder, and the AppData folder, but there is no duplicate add-on either.

How can I get rid of the warning? Is there a statement I need to execute in the console? I'm using Windows 10 i7 processor

    $\begingroup$ Check the system console blender.org/manual/interface/window_system/console_window.html , not the python console. The offenders will be in your addons folders. $\endgroup$

In windows OS you can open the console form the menu:

Window->Toggle System Console:

enter image description here

There you should be able to find information on your error.

In your case you have a duplicated addon. This error can happen when you have two versions of the same addon as well.

The duplicate could be in two places:

On the programs folder in your system drive:

  • C:\Program Files\Blender Foundation\Blender\ version number \scripts\addons

or on the App data folder:

  • C:\Users\ your user \AppData\Roaming\Blender Foundation\Blender\ version number \scripts\addons

Open both folders, find the duplicate and remove it from the folder.

Then restart blender.

  • $\begingroup$ This works like a charm... I would add to the answer, like in my case, I reopen the application, and nothing was shown in the Terminal, I have to open the User Preferences dialog, then the duplicate files were shown with the error in the Terminal. The funny thing was that the add-on that I thought was causing the error was not the culprit. $\endgroup$

I had the same error at one point, so I will expand on Cegaton's answer with what the solution was for my case as it may be helpful. The duplicate files may also appear in the addons_contrib folder.
