    Perhaps you need to add Local Activation rights for the asp_net account.

    1. Open Component Services
    2. Expand DCOM tree
    3. Find Excel Document
    4. Right click on the element, select properties
    5. Go to the Security tab, select Customize-> Edit
    6. Choose an asp_net account and set the Local Activation flag for it.
