Hi yes i tried same solution before deployement. this is my Web.Config file.

Try not deleting anything from web.config. And copy Microsoft.Office.Interop.Excel manually to your application bin directory.

Praneeth Kumar · Answer

Did you try the same sol.n locally before deployment??? Can you post a sample project if possible???

Lakshmi Narayan J · Answer

I have already added that dll (Micrsoft.office.interop.Excell.dll ) but its showing same error.

Praneeth Kumar · Answer

Well did you put the interop excel dll inside the bin folder. If you have not then pls do that and try running the application again.

Lakshmi Narayan J · Answer

Hi Praneeth Thanks for reply. I have deleted that public key in my web.config file. Now I am getting the following error. 500 - Internal server error. There is a problem with the resource you are looking for and it cannot be displayed. Thanks & Regards Lakshmi.

This means the hosting server does not have Microsoft.Office.Interop.Excel version 11.0.0.0 assembly installed in GAC. What you need to do is when you are publishing project you can opt to include the assemblies you have referenced this will copy the assemblies in your project bin directory.

Praneeth Kumar · Answer

I believe the deployed server does not have microsoft excel dll in the GAC. What you can do is put the same Microsoft.Office.Interop. Excel Version=11.0.0.0 in the bin folder and remove the attribute publickeytoken from your config so that your application searches the bin folder than the GAC folder.
