Acrobat 9 pro and Admin user/password

Question

Every time Acrobat 9 pro on my Mac (OSX 10.6.1) is launched it sakes for my admin user/password. If I enter the info in every time I launch Acrobat 9 pro admin it works, but the next time I login with my network user account Acrobat 9 pro want the admin user/password again.  What might be causing Acrobat 9 pro to want admin user/password.

Answer 1

If, as it it says on top of the page, the question is "possibly answered", the "1 correct answer" is not shown.  The mystery and annoyance remains.
Acrobat 9 Pro (installed as part of CS4 Design Standard by the same admin user that now wants to use it, OSX 6.7) asks for my password every time I start it:  "Type your password to allow Adobe Acrobat Pro to make changes."  The only necessary change that I see is upgrading back to version 8, which didn't suffer from this bug.
When I click cancel (twice – the window returns once.), I'm told that "Adobe Acrobat could not install correctly.  An invalid password or user name was entered.  Adobe Acrobat will now quit."
To repeat it, Acrobat is already installed, and I've entered the username-password combination several times correctly to use the software, but it's not acceptable to do that every time in all eternity.  Please, Adobe, fix this quickly or give solution if one exists.
