What Exactly is Error FRM18105?

Before diving into the fixes, you need to understand the architecture. In Oracle Forms (6i, 9i, 10g, 11g, and 12c), when a user requests help, the Forms runtime tries to launch an external WinHelp (.hlp) or Oracle Help for Java (OHJ) engine. FRM-18105: Failed to start the help system

The error code breaks down as follows:

• FRM: Oracle Forms message.
• 18105: A generic failure code indicating the Forms runtime successfully called the help system, but the help system returned a "launch failed" signal.

In simple terms: Your form wants to show a help page, but the helper application (the viewer) isn't working correctly.

Solution 1: Verify the Help System Configuration

1. Check the forms.cfg file for the correct help system settings. The file is usually located in the ORACLE_HOME/forms directory.
2. Ensure that the HELP_DIR parameter is set to the correct directory path.
3. Verify that the HELP_SYS parameter is set to the correct value.

Example:

HELP_DIR=/path/to/help/directory
HELP_SYS=ON

5. Re-register the help DLLs

Open Command Prompt as Administrator and run:

regsvr32 "C:\Windows\System32\hhctrl.ocx"
regsvr32 "C:\Windows\System32\itss.dll"
regsvr32 "C:\Oracle\bin\frmhelp.dll"   (adjust path as needed)
