Error when launching DBA - I/O error for file "\System.fdb"
The "I/O error for file "\System.fdb"" error can occur if the DBPath.txt file is missing or incorrect. The DBPath.txt file should be located in the main directory of the DBA Manufacturing folder on the server.
If there is no DBPath.txt file in the main directory of the DBA Manufacturing folder, or the path to your main company database in the text file is incorrect, this is a possible source of the issue.
