So... first attempt at writing my own DataPlugin. Done in LabVIEW using the DataPlugin SDK.
I tested it within the project it works. Ran the installer and ran the "Register LabVIEW DataPlugin.exe" that comes with the SDK.
... it doesn't seem to work. If I go to Settings -> Extensions -> DataPlugins... it doesn't show up in the list. However, if I then click on "Import DataPlugin", mine shows up in the DataPlugins folder. Not only that it has a .uri file. If I try to import it I get a dalog box that says "You have already registered..."
What am I missing?
