Procedure for deleting a Trial License
.....
In the Explorer you mark the "AX NF ZZ" directory on your hard disk or on drive "C", so that the file names of the licenses are displayed in the right window of the Explorer.

If the "AX NF ZZ" directory or the files in that directory are not visible, then open the dialog "Tools > Folder options..." and select the "View" tab:

· Here you deactivate the option "Hide protected operating files (Recommended)" and

· Activate the option "Show hidden files and folders".

Then click on the "Apply" button and acknowledge with "OK".
