You have to open the workbook. The macro is data in a file - Excel
interprets it, makes it executable code and executes the code. To do this,
it has to open the workbook.

How do I get this to work?

Private Sub btnUpdateLifeCycle_Click()
Dim strMacro As String

strMacro = "\\arlfs03\shared\Engineering\ENG\BOM Archive\" & "'" &
"BOM_Macros.xls" & "'" & "!UPDATE_LIFECYCLE_SUMMARY"

Run (strMacro)

End Sub

I want to fire off a macro without having to open and close the
workbook containing the macro.
