Any idea how to install an .fmaddon file in a Windows environment? Trying to get the new OttoReceiver package working but manually installing the .addon into the /AppData/Local/FileMaker/Extensions folder does nothing and following the instructions here by double clicking the .addon file and trying to open it with FileMaker results in a ‘The translator for this file format could not be found or could not be initialized’’ error.
Hmm, Double clicking is supposed to work on windows
But you can install it manually. I don’t have a windows machine handy to look at the exact path, but on mac it is
/Library/Application\ Support/FileMaker/Extensions/AddonModules
It should be in the same general vicinity as where plugins go.
Put the file in there, then quit and reopen FileMaker.

In my Windows version, there was no file association for the .fmaddon file type, so I just chose FileMaker…not sure if that’s what I should have done, but since Windows didn’t know how to handle it that’s what I did.
As far as the manual installation, I installed to %localappdata%\FileMaker\Extensions\AddonModules which sounds like the right directory. I’ve restarted, but when I go to the addon tab, I only see the default Filemaker addons.
NM, I had my Mac handy and installing it via macOS worked fine.

@toddgeist Unfortunately we don’t own a MacOS PC and I also have the same problem. I’m not able to install the add-on even when I put it directly in the correct folders.
Hi Marccie
Welcome to the community. 
What folder are you putting it in. It can be tricky to find the right folder on windows.
And Did you restart FileMaker after manually installing the add-on file?
Here is another forum past with a video that might help. In case it is the wrong folder.
Let us know if this helped.
Thanks

Hi Todd,
Thank you 
I’ve putted in the “C:\Users_USERNAME_\AppData\Local\FileMaker\FileMaker Pro\21.0\Extensions\AddonModules” so the standard folder for the plug-in. Also tried “C:\Users_USERNAME_\AppData\Local\FileMaker\Extensions\AddonModules” and “C:\Program Files\FileMaker\FileMaker Pro\AddonModules” restart FileMaker but no results.
Opened FileMaker with administrator settings als no results.
So yeah basically tried everything…
I can try to create a virtual machine with MacOS but that’s more a hassle.
Hi Marccie
One more thing, that catches me sometimes. You have to click the little tiny plus button at the bottom of the Addons window. You can barely see it.
If that doesn’t work. you don’t really need the add on. You can just add a Table called OttoReceiverInbox, with two fields
- Channel
- Payload
Add a layout with those two fields on it called “OttoReceiver”.
And then add a script Called “OttoReceiver”. Modify it like this.
That’s it.
Thanks
Todd
