Insert VBA Helper: access denied - SOLVED

My excel sheet is saved. In its Visual Basic Editor is active the empty “Modul1”. Now I compiled code Sub test(Param1) from the XLS Padlock Guide.
Problem 1: After pressing the “Insert VBA Helper in VBE”-Button there is no insertion, but the Excel Error message “Der programmatische Zugriff auf das Visual Basic-Projekt ist nicht sicher”.
Problem 2: After pressing the “Show Visual Basic Editor”-Button there isthe Excel Error message “OLE error 800A03EC”.

How to go on?

This requires that you enable “Trust access to the VBA project object model” to let XLS Padlock access your VBA Project. Go to Excel Options > Trust Center > Trust Center Settings… > check “Trust access to the VBA project object model”. Failure to do so will result in the error message you mentioned “Programmatic access to Visual Basic Project is not trusted” when compiling your project.
