The file does not contain any valid add-ins
I'm trying to add an add-in, but the following message appears: "The file does not contain any valid add-ins."
The Add-In is very simple, based on the "RightNow Workspace Add-In" template. I just added a "switch" in "RuleActionInvoked", compiled it and tried to add it in RightNow.
I've already uninstalled and deleted the folder located under "Roaming".
Any idea what I can do?
