Windows Batch File Instructions


If you are running DBA version 397.0.0 or higher you can use the Windows Batch File instead of doing the manual uninstall steps listed below.


Do keep in mind that running the Windows Batch File will immediately delete the entire DBA Manufacturing folder including the database (ejdb.fdb file).  It is very important that you make a backup of DBA before doing the manual uninstall.  The Windows Batch File will also delete the DBA Training Company, Firebird 3, and the Windows Desktop shortcut icons for DBA.
