App Crashing on some Windows XP

Hello everyone,
I have a strange emergency situation. On a specific PC (that is a touch screen CASIO POS), our application seems to crash with the following (non descriptive) error.

I tried everything that I could imagine, but with no success. On our own XP installation the application runs with no problem.

Only very simple applications don’t crash for example a window a few controls on it…

One of the differences is that the POS has only 512Mb RAM. Could this be the problem?

Thanks in advance for any ideas…

I can see the problem is in the DB plugin. Do you have the SQL Native Client installed on the device?
