Microsoft.Office.Interop.Excel 500 Error on server

I am using Microsoft.Office.Interop.Excel nuget package with asp.net mvc project. I am trying to read excel files. Everything works perfectly on my localhost but when i publish them to my hosting it gives 500 error on this line;

Application xlUygulama = new Application();

Everything is ready for use, so i don't want to change framework.

Microsoft does not currently recommend, and does not support, Automation of Microsoft Office applications from any unattended, non-interactive client application or component (including ASP, ASP.NET, DCOM, and NT Services), because Office may exhibit unstable behavior and/or deadlock when Office is run in this environment.

If you are building a solution that runs in a server-side context, you should try to use components that have been made safe for unattended execution. Or, you should try to find alternatives that allow at least part of the code to run client-side. If you use an Office application from a server-side solution, the application will lack many of the necessary capabilities to run successfully. Additionally, you will be taking risks with the stability of your overall solution.

Read more about that in the Considerations for server-side Automation of Office article.

If you deal with open XML documents only you may consider using the Open XML SDK instead, see Welcome to the Open XML SDK 2.5 for Office instead. In other cases consider using any third-party components designed for the server-side execution.
