Form Controls MS Office excel and LibreOffice calc

Hello,

does anybody know what else besides MS excel (or Libre Office Calc) do i need to have installed in my computer to be able to use Form Control Buttons?
(to avoid confusion, Developer tab / Controls / Insert / Form Controls / Button)
on computer 1 i have MS Office and Libre Office installed, and it works perfectly in both of them,
on computer 2 i have only Libre Office installed and it doesn't work at all. the settings in the Libre office are the same on both computers (for example Macro security)
on computer 3 i have only Libre Office installed, it works perfectly, but i can't find out what the additional program is, that makes it work.

example of the code:
Sub add1_Click()
For x = 16 To 70
Cells(x, 5) = Cells(x, 5) + Cells(x, 9)
Next x
For x = 16 To 70
Cells(x, 9) = 0
Next x
End Sub

my question is, what else besides Libre Office Calc do i need to have installed on computer 2, to be able to use the Form Control Buttons.

thanks
