Let's go back to the title of this thread. I just received a (great) Fujitsu ScanSnap 1500 scanner for my MacBook Pro (Lion). Along with the scanner was a copy of Acrobat Pro 9 for Mac, one of this reasons I went for this scanner at the present time. The disk is Acrobat Pro 9.0, which is fine. What is NOT FINE is the burden of installing NINETEEN sequential upgrades!! How many hundreds (thousands?) of hours are wasted by Adobe customers as a result of this ridiculous policy?
For YEARS, software developers have offered full upgrades, at least for every major version (e.g., 9.1, 9.2, 9.3). As stated earlier (and especially since Acrobat 9 is no longer under active development), why can't you do a series of upgrades AT ADOBE, and then offer an unregistered download. This would make the download available only to users with a valid license key, and save them hours of work.
At the very least, (Note: Bold, italics, AND underline!) you could bundle all the downloads into one (or perhaps 2 or 3) zip files so we don't have to sequentially navigate through THREE WEB PAGES for each of the nineteen upgrades. Let's see - 3 X 19 = FIFTY SEVEN PAGES I have to visit just to obtain the files. Then I have to wait for the download, mount and open each one, type in my system password, and wait for the installation.
ADOBE -- GIVE US A BREAK!!! This is an indefensible customer support fiasco!!!
(Pardon me for 'yelling', but there are circumstances in which yelling is called for. This is one of them. In fact, this situation is probably deserving of more than 'yelling', but I don't wasnt to get booted off the site. Besides, there may be children listening.)
