Trying to upgrade to ArcGIS 10.4.1 on Windows 10, MacBook Pro bootcamp (mid 2012). Everything went smoothly, until I attempted to open ArcGIS Map, whereby I received the following message: "The application was unable to start correctly (0xc000007b). Any ideas???
The files under the AppData location are created by the running ArcGIS Desktop applications. The setup program doesn't create them on installation, move them on an upgrade or delete them when uninstalled. They may not be present if the application was never successfully opened to migrate them from the 10.3 to the 10.4 folder.
