createobject failed !

Hi,

I just installed "Adobe Acrobat Pro DC" and try to use it through Automation.

I checked "Adobe Acrobat 10.0 Type Library" in references and wrote an Excel macro:

Sub Adobe()

    Dim app As Object

    Set app = CreateObject("AcroExch.App")

    app.Show

End Sub

When executed i get an automation error "Error not specified" on the "set app = ..." line.

I still get the error after "Repair installation".

What do i missed ?

Please help.
