Hi,
yes i tried same solution before deployement.

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

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

I have already added that dll (Micrsoft.office.interop.Excell.dll )
but its showing same error.
Praneeth Kumar15y ago
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.

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.

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.
