Hi:I debugged the crashed CE8 in newest win10 version. the main problem is ucrtbase.dll as some post said. But the software run on the win7 is puzzled me. the MicroStation CE8 stop working when open a document. but the OPM and AECOsim work well. I checked the ucrtbase.dll, it's no change recently. is some thing can be done by Bentley to avoid the crash.
