Again, it might be some specific mapping letter, e.g. maybe just these two machines have CD-ROM drive 'H:', and exactly this letter is hardcoded in some SCX file. Normally, if 'H:' is just hard/network drive it will not generate an error, because app just look there, cannot find something and proceed to SET PATH way. The 100% reliable way is to forget about SET PATH and reset DE.Cursor.Database properties programmatically.
