Welcome to the forum.
First, software in the last 4-5 years (maybe longer) do not come out with manuals anymore. If you are talking about the help file they are all on line now. Besides, what version are you looking for?
If this solved your issue please mark this posting "Accept as Solution".
Or if you like something that was said and it was helpful, Kudos are appreciated. Thanks!!!!
You can download a local version of the Help files.
Is that what you are looking for?
