Hi, I'm trying to get Revit 2017 working on a macbook pro 15 running parallels 12 and windows 7. Install went without a problem and Revit opens, but when opening/starting a project and getting into the work window I suddenly get a error message saying" An unrecoverable error has occured. The program will now be terminated. All of your data has been recently saved, so there is no need to create recovery files ". I have reinstalled, repaired and downloaded the latest updates for both window 7 and Revit 2017 and I'm starting to run out of ideas. Help is much appreciated! Best regards
