In my module,

I want to open a word document. When I click a button will open it.

I use the the Microsoft Word 9.0 Object Library. First I try it on a .aspx file, it worked. Then I made a dnn module,

When I click my button the document couldn't be open. And give that error message

Retrieving the COM class factory for component with CLSID {000209FF-0000-0000-C000-000000000046} failed due to the following error: 80070005.

This error message means, there is a permission problem on the reach word component , or it isnt installed.

I try different library, for open the word document but none of them worked

Here my code sample;

Application app = new Application();

app.Visible = true;

object visible = true;

object fileName = GetAppPath() + "/KoliAcmaTutanak.doc";

 object optional = System.Type.Missing;

Document doc = app.Documents.Open(ref fileName, ref optional, ref  optional, ref optional, ref optional, ref optional, ref optional, ref  optional, ref optional, ref optional, ref  optional, ref optional, ref optional, ref optional, ref  optional, ref optional);

Thanks
