Hi Masterofdisaster1020,

Is Excel installed on your web server? It has to be installed in order to be instantiated.

It may be a permission problem. Is the user under which IIS runs has access to Excel?

everybody, including the IIS WPG has full control on the Excel Application.

Open the References of your project, click on Excel and Office core and set their "Copy Local"^property to True. This will adds new DLLs in your bin folder. Be sure to copy these dlls to the server.

Cause I did not found the property, I just deleted the complete Bin dirctory and re-imported the refferences of microsoft excel 11.0 lib, but it isn't a solution.
Éric MoreauSenior .Net ConsultantCommented:

From the solution explorer, open the "References". Click on Excel. Then in the Properties dialog, you will see the "Copy Local" property.

I'm working with visual web developer 2005 express edition. Could it be possible there is no possibility to change property's of the references? There is also no reference tab in my sol. expl., like it is in visual studio 2003.

When I import a reference into the project, I only become the BIN directory with the appropriate .DLL s.
Éric MoreauSenior .Net ConsultantCommented:
In a 2005 Windows Forms application, to find the references, I have to open the properties of the project (Properties from the Project menu). in the tabs on the left, you will find "References". Click on it. Select Excel from the list and in the properties dialog you will find "Copy Local"
