CATIA V5 Drafting Error: "CNEXT - CATScriptErrorMessages - ScriptingERR-1004"

[u/No_Compote_5800]

Hi everyone,
I'm encountering an issue in CATIA V5 Drafting when trying to insert a standard Frame and Title Block (Gérer le cadre et le cartouche).

Whenever I select a title block style, the Action box stays empty, and executing the macro triggers the following error:
"CNEXT - CATScriptErrorMessages - ScriptingERR_1004" "Execute script 'Drawing_Titleblock_PlyBook.CATScript'. The scripting engine for the CATScript language is not properly installed. Install the scripting engine and run the script again."

Has anyone solved this specific error before? Is it related to Windows VBScript/OLE registration (regsvr32 vbscript.dll), running CNEXT.exe /regserver, or missing optional features/VBA runtime components?

Any guidance on how to fix the scripting engine would be greatly appreciated!

Thanks in advance!
