The following possible error responses may be displayed in the Terminal Emulator pane of the Options dialog box (Tools > Options > GUI Testing tab > Terminal Emulator node) when you click the Validate button.
Invalid HLLAPI DLL
The required HLLAPI or EHLLAPI function cannot be found, because the configured DLL is invalid.
Ensure that you have configured the correct DLL path and name in the Terminal Emulator Configuration Wizard (Tools > Options > GUI Testing tab > Terminal Emulator node > Open Wizard).
For more details, see the table listing the DLL names used by supported terminal emulators in Configure HLLAPI Properties Page, or the documentation provided by your emulator provider.

-
Ensure that the terminal emulator main window class name is configured correctly in the Terminal Emulator Configuration Wizard (Tools > Options > GUI Testing tab > Terminal Emulator node > Open Wizard).
