Reader Extensions can be bought as a module in LiveCycle. There is a subset of RE functionality that exists in Acrobat. The ability to save locally is part of Acrobat. In both cases you woudl RE the form before distributing it, hence when the user gets your form they are ready to go. You can download a trial version of the server product. As far as pricing goes you woudl be better to talk to an Adobe salesrep as there are discounts for certain situations as well as different pricing options. If you decide tp gp the Acrobat route you ar limited, by licence, to distribute your form to a max of 500 users.
Hope that helps
So if you only need this for one form
and three users are you better off just to buy Acrobat Pro for
three users? There is not any more alternatives for database connections?
Actually, i got the answer from the sales rep.
You can unlock a form in Adobe Pro to allow users to save it halfway through. It's part of the functionality of the application and doesn't require reader extensions. I believe this only applies if the number of users is high, which in my case, isn't.
