I have developed the website which is working fine normally.
I have added web reference of the COM->Microsoft Excel Object Library version 11.0 in that application.
This works fine when i execute from the Visual Studio 2008. But when i publish the site into IIS then I am getting the error that "instance object not found" for the class which is into that DLL.
I also tried with the creation of VIrtual directory. But then also getting same error.
So is there any process to add reference while publishing the site?
