Class does not support Automation

[bronc]

Hello
I am using this code from Excel.

Option Explicit

Dim appWord As Word.Application

Sub AddData()
Set appWord = New Word.Application
End Sub

and I get this message.

"Class does not support Automation or does not support expected interface"

I have tried the exact same code on other machines with identical references set in Word VBA and Excel VBA and it works fine.

Thanks
