If you are importing an EXE file into Excel, follow these steps:
- Paste - Object
- Select tab: Create from file
- View exe file
- Check "Display as Icon"
then you can write a VBA / macro routine (I used a rectangular shape object to execute the macro by clicking on it):
Sub RoundedRectangle1_Click()
Dim ws As Worksheet
Dim oo As OLEObject
Set ws = Sheets("Sheet1")
Set oo = ws.OLEObjects("Object 1")
oo.Verb xlVerbPrimary
End Sub
