Macro to run .exe located in other computer

I need to get a macro to run an .exe file that is located in another machine but the macro cannot locate the file.
I have a network drive mapped as M: and tried both

Private Sub CommandButton1_Click()
Dim RetVal 
RetVal = Shell("M:\03 - Tech\get fuel data.exe", 1)
End Sub

and

Private Sub CommandButton1_Click()
Dim RetVal
RetVal = Shell("\\generator-pc\\03 - Tech\get fuel data.exe", 1)
End Sub

Both of them give a Run-time error '53': File not found.

When I run that scriot for a file located in the computer where the macro is running it works just fine. How can I get it to run the .exe in the other computer?

Thanks in advance!
