This might classify as a windows thing, not just an 'Access' thing
because it effects any program that uses a DATABASE with access-based file system even if Access is installed or not...
Windows XP Home, sp3, Office XP sp3:  recently started having a
problem with not just Access databases but being able to open a
program that uses an "Access-based form of database" (a program that
doesn't require Access installed, yet uses an access-based database) I
first noticed it yesterday when I tried to open my PHOTOSHOP Album
program and it failed. I went to my database of "program discs" (to
find where my adobe DISC was to reinstall it) and Access was all
screwed up too.

I totally removed office XP, reinstalled and still get the FOLLOWING
error: When I open a database and click on a table or form it pops up
(the yellow exclamation mark) "Unknown" that's it, Unknown (then it
gets the "Access must close now...").
I knew the Adobe used an access based form of database and even after
reinstalling, it's error says when I open the program: it says "The
ODBC data source reported the following error: INTERNAL error, data
not found"

The databases work fine (both Access and Adobe) on my laptop that
hasn't been cleaned with the CCleaner so I know it's not just the DB's
themselves.

Is there something in the registry I should look fore to change or put
back if it's missing?
