Thrown many times in the install.log

Cause

This can happen for two reasons:

• The OS still holds a lock over the files and prevents any updates to them
• The original Clarity folder files got corrupt by the previous install attempt

Resolution

• Restore another Clarity folder from a backup and restart the upgrade
• For OS locks, sometimes a server reboot would help as well
