I want to use the ReCaptcha widget by ProfitScience that's in the app store. The app store will only let me download it in v5.21.5 or below of the Modeller. I've installed that and the widget downloads but then it says it was created in v6.4.1 of the Modeller and won't open it. I then installed v6.4.1 of the Modeller but the app store won't let me download the widget! I've tried contacting the author of the widget but got no response. Can anyone shed some light on how I can get this widget working (preferably in 6.10.3 which is what we're working with at the moment)?
if you already have downloaded the widget with the 5.x modeler, you can just copy it to your projects widget folder (press F4 to sync) and test if it works.
If it doesn't work then follow the advice by Chris, or contact the author of the widget.
