Hi AeroX,


I've never personally seen issue with ucrtbase.dll , is this the only event that you see in the Event Viewer when the software crash ? Do you see any other event complaining about different dll's ?


With quick google search about that dll , it seems the issue might have something to do with Windows update


(e.g., https://forums.autodesk.com/t5/installation-licensing/windows-10-update-1709-16299-19-inventor-2017-crash-when-open/td-p/7484704 


You can try like what mentioned there; however, for ANSYS software, I would recommend to just check any pending Windows update and make sure you install all of them. 


Also, go to this directory C:Program FilesANSYS IncANSYS Studentv191prereq , then run every executable one-by-one with 'run as administrator' .


Thank you,


Win
