Cann't connect MF to Excel

Hello, cann't connect MF Pro to Excel 2021 with existing Worksheet. I click on Excel logo in MF Pro, but no connection. Connection with new Worksheet is OK. But I want to open data in existing (open) Worksheet with macro. I tried to tip and untip all checkboxes. But no result.

Hi there

1) Click all the options in setting/excel you wish to appear on your spreadsheet

2) Open your spreadsheet in the background

3) Click launch excel and it will ask if you wish to attach to the existing excel instance or open a new one
