Opening Excel workbook from ASP.NET WCF Web Service HRESULT: 0x800



Hi all,
I'm trying to develop a C# WCF Web Service method to open and manipulate an
excel file programmatically.
I was getting error "Retrieving the COM class factory for component with
CLSID {A1093992-8BEB-4307-943B-3FF7023AD1E2} failed due to the following
error: 80070005" while accessing application so I changed DCOM permissions.

Unfortunately now I'm getting error "Exception da HRESULT: 0x800A03EC" while
opening workbook. The problem occurs only when service in deployed on IIS
server. In debug mode (with WCF host) the problem is not present.

Could anyone help me finding out where is the error?

Thanks in advance for the help
