I click on Help->Adobe Acrobat 9 Pro Help ...
and nothing happens.
Nothing happens if I hit F1.
Nothing happens if I try Help->Online Support.
So here I am with yet another stupid membership asking a question I don't think ought to need to be asked.
It's 9.1.2 actually, your list hasn't been updated yet.
--the help files are where they belong and will open if the files are double-clicked
--repair did not repair
One suggestion was that using the custom option (as supplied in the installation program from adobe and which really only lets you opt to not install some components) is the culprit. I should have realized that it would come down to user error. I'm terrible that way, wanting my system set up my way.
I looked off-site. No joy.
Finally I ended up uninstalling adobe cs4. This caused my sound to disappear. But, since solving the adobe installation problem seems a terribly difficult thing, I won't ask about that. It's all right though, I got it back thanks to helpful people on other forums.
I re-installed and was happily surprised that I did not have to reinstall my old cs first. After going through the extraordinarily long install I found that ... I do not have help files available from the programs. Again. Unhappily, I wasn't all that surprised.
I uninstalled again. (Amazing how the hours drag by!) Tried again. This time I did not change anything during install, I just agreed with whatever adobe uses as it's defaults. Wouldn't want to upset the program, you know. Again no help files. Again, not surprised. Well, I need to amend that. A few components opened up, some wanted the serial number but wouldn't accept it. Those that opened up did not open the help files.
I have completely stripped my system of adobe and will probably try again. I am curious why adobe feels the need to change the security restrictions on sample and template files. But, I was able to delete those too. So, my system really is adobe free. No cs, no reader, no flash. Feels good, actually.
