Excel Crashes when trying to Open Word Document

[recarv]

Hello,

I've got a problem where I'd like to have a word document open from Excel, It seems that I can start Word alright, but any attempt to open a file causes a crash. This makes me think I have the syntax wrong or something. Please help.

If Module1.dhFileExists("C:\instagram\Instagram_Manual.doc") Then
        Dim wdapp As Word.Application
        Dim wdDoc As Word.Document
        Set wdapp = CreateObject("Word.Application")
        wdapp.Visible = True
        Set wdDoc = wdapp.Documents.Open("C:\instagram\Instagram_Manual.doc")
        Set wdDoc = Nothing
        Set wdapp = Nothing
    Else
        MsgBox "Manual was not found."
        Exit Sub
    End If

If I comment out the Set wdDoc = wdapp.Documents.Open("file") line, Word opens fine. If I don't, I have to send an error report to the great bit bucket in the sky that is Microsoft Development.

Please advise.
