Hello:
The following is displayed on the Help Menu topis of the help manual (I don't know if you call it a help manual or help file):
"The Help menu provides links to documentation, support, information about GDT, how to purchase a license for GDT and how to enter your license into GDT."
Then four items are listed as appearing on that menu. As a purchaser of the software I only see two: Help Topics and About. It might be a good idea to just indicate that only two are displayed if the software is purchased and and the key is entered.
Best regards
Joseph
