This error message appears when you install an evaluation copy of SwiftView and its active period expires.
Note that SwiftView licenses are not compatible with evaluation executables. If you install an evaluation version of SwiftView and puts your license in the SwiftView directory, you will still receive the error.
To resolve this issue:
You must have a current license. If not, you must purchase a license.
Uninstall SwiftView from the PC, delete the evaluation installer, download a production SwiftView installer and run it. The take the unzipped license file and place it in the SwiftView directory (usually C:\Program Files (x86)\SwiftView).
