This error occurs when a production version of SwiftView cannot find a license. If the user’s copy is supposed to be licensed, then the license is in the wrong location or SwiftView is looking in the wrong location. If they are not supposed to be using a licensed copy of SwiftView, then they must use a licensed/stamped file or be viewing documents on a licensed website.
To resolve this issue:
Please contact Licensing@PAPERBOS.com, including the hostname and/or ID number of your license.
