Path name is wrong and cannot even compile. Use verbatim string literal format @"..\..", or escape each \ with \\. Use relative or absolute path, "~\.." won't work. Read about valid path names in any manual for the OS users.

Anyway, there are no situations where hard-coded path name can be used in production-grade software.

Solution 2

In addition to Solution 1 -

You also need to consider what you are attempting to do. I hope that you do know that you are attempting to open Excel on the server? Think about it for just one second, since your code runs on the server then it will attempt to open Excel on the server.

And before you ask why it works on the localhost, the reason is that you development machine is both the client and the server.

Have the client download the Excel file and handle it locally.

If you describe what you are attempting to do we would be in a better position to help you.

Why would you want to open Excel on the server to start with?
