Frm-18105 Failed To Start The Help System May 2026

Oracle Forms locates the help file using a registry key. For Forms 6i:

HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\FORMS60_HELP_PATH

For Forms 9i/10g:

HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\KEY_DevSuiteHome1\FORMS90_HELP_PATH

Required value: The full path to a valid help file, e.g.,

Each Forms module has a Help property (under the Form node in Forms Builder). This property should contain the full virtual path to the help file, relative to the Forms application’s web context.

Example: If your help file myapp.chm is placed in $ORACLE_HOME/forms/help/, and your Forms servlet is mapped to /forms/, set the Help property to: Oracle Forms locates the help file using a registry key
