Customization Folder Required File Permissions
The Design Master Electrical customization folder must be set to read-write for our software to work. The files in the folder can be read-only if you want to limit who can make changes to them.
This permission is needed because the Jet database driver that we use needs to be able to create a temporary lock file in the folder when it opens the database. If you do not have permission to write to the folder, this file creation will fail.
This applies to the customization folders for all CAD-based Design Master products.
