Almost there!
When I have it like this, KaraFun Plyer opens but it doesn't start playing the song, it just opens the player and nothing else happens:
Code:
Private Sub CommandButton1_Click()
Shell "C:\Program Files (x86)\KaraFun Player\KaraFunPlayer.exe" & " " & _
"C:\Users\P\Desktop\Karaoke\Karaokes\Phil Collins - Another Day In Paradise.zip"
End Sub
In this pc I'm using Excel 2013, I don't know if it matters.
