When I try to insert a cavity I get an unhandled error? How do I resolve the issue?

If you see the following error message when inserting a cavity, it is most likely you do not have full permissions to the settings folder of MDTools.

Provide full permissions to the user profile for the following folder.

C:\ProgramData\VEST\MDTools 955

Also add Everyone to the list of users and allow Full Control.
