There is a bug in Dell's Backup and Recovery software that is causing any 64-bit application which uses the Qt5 core DLLs to crash. The below are the 2 methods to fix.
1st Method: -
Apply Fixed Patch
1) Make sure Dell's Backup and Recovery software is installed.
2) Confirm the installed path was under C:\Program Files (x86)\Dell Backup and Recovery\
3) Copy the Fixed Patch zip file from https://ftp.reallusion.com/reallusionsupport/Fix_for_DELL.zip to local drive and un-compress it.
4) Double click to run "UnregisterDellShellExtension.bat".
Note: If to restore from the Fixed Patch, just double click to run "Restore.bat".
2nd Method: -
May uninstall the AlienRespawn or Dell Backup and Recovery application that is responsible for the crash.
This utility software is pre-installed on new Dell and Alienware computers and is incompaiible with iClone 6.
