NL View Profile Send Message MikiMuzsi PEGA replied to HAUGV Hi, On a clean image (without any preimported zip/jar files), can you please follow the exact steps from solution video and let us know at which steps do you get this error? Deleting virtual box, and the ruleset would not help. Also, the browser version would not make a difference. You just need to ensure you have a clean image. Miki p.s. Before running the app overlay wizard, check if that ruleset physically exists.
