Windows 10 Spring Creator Update (1803)
There is a known issue with the Windows 10 Spring Creator Update, 1803 with numerous Bentley CONNECT Edition software. MicroStation CONNECT Edition can refuse to start. OpenRoads Designer CONNECT Edition appears to start correctly but encounters errors on actions involving corridors. The links below include information on how to rollback the 1803 update, and Bentley is recommending that you do so until the updated fix has been released.
