Vista, Office Interop not working


Does anyone know how to get the MS Office 2007 .NET C# Interop libraries to work with Vista?

I have a .NET C# application that I have setup to run as a Windows service. This program will open up a Word or Excel template depending on the situation and modify its contents and then save the document back out. All of this worked great when I was doing it on a Windows Server 2003 or XP machine using Office 2007. When I moved everything to a Server 2008 box, everything quit working. In Excel for example, I get a COM exception telling me that the Excel file cannot be opened when the file is clearly there and I can open it just fine when doing it manually. The windows service is running under the same user account that I log into the machine with and that account is an Administrator.

Does anyone have any idea what to do?


Solution

  • You should really avoiding running the Office clients as server side apps. Consider using xml as file format (xlsx for Office 2007, or using the Excel workbook xsd for (somewhat) older versions.) Then you would be freed from using the Excel API on the server.
