strace was already mentioned, which is a good idea. Look near the end of
any log for something = -1.

But before you go that effort, type "which acrobat" (or whatever name it
uses) from each user, see that they use the same one. Assuming they do,
cd to that directory as root, and do "ldd acrobat". Then as your regular
user that is failing, cd to whatever lib directory contains the named
libs, and see if that user can use "nm" on all of them (this reads
symbols). This will find out if your user does not have permission to
access a particular required shared library. If you find one that is
refused, use root to chmod it to readable by the failing user. It sounds
like permission has been lost somewhere (since it appears the config
file has already been tested as the cause).
