Word Automation : could not open macro storage

Question

My application (vb.net windows application deployed via ClickOnce) uses Word to open and fill .dot templates to create new Word documents. I reference Microsoft Word 14 Object Library and uses this code :

Dim oWord As Word.Application = Nothing
Dim oDoc As Word.Document = Nothing
Try
    oWord = New Word.Application
    Dim strFileName As String = ""
    Select Case strType
        Case "LettreReception"
            strFileName = Path.Combine(GetParam(1), "Template_LettreReception.dot")
            If File.Exists(strFileName) Then
                oDoc = oWord.Documents.Add(strFileName)

On the last line I receive "could not open macro storage" error on deployed machines (not on my development machine).

I develop with Windows 7 - Office 2010 - VS 2010 (.Net 3.5). My deployment machine is also a Windows 7 with Office 2010 installed.

I tried to remove normal.dotm (I found some links advicing it) without success. The .dot template used contains no macro.

Answer 1

Check the properties of the word document and make sure the files are unblocked. Sometimes when you get the documents from a different computer or download them from the internet they will be blocked which will cause the the throwing of this exception "could not open macro storage"
