Sure it's opening. It's opening on the server just like you told it to.

C# code is executed at the server, not the client.
It worked in testing, because they were the same machine, so the same folders were available to the client and the server. Now, when you release the code, the server and the client are different PC, perhaps thousands of kilometers apart, and the Server cannot access the Client hard disk at all, for security reasons.

There is no way round this: if the server needs to open the file, it must be transferred from the client to the server first, and then opened - and that has to be done by the client, not the server as it can't access the client HDD at all.

Even if it could, the Process you started would run on the Server, not the Client, so the user would not see it at all - it would start to annoy the heck out of your web host administrator though...

I have solved this issue in another way.After writing the content into text file.I wrote the content of ReleaseNote.txt into the TextFile.aspx page again.This is something as follows within page load event of that page.

    protected void Page_Load(object sender, EventArgs e)
    {


        string filename = "ReleaseNote.txt";

        try
        {
            if (!Page.IsPostBack)
            {
                Response.ContentType = "application/octet-stream";
                Response.AddHeader("content-disposition", "attachment; filename=" + filename);

                FileStream sourceFile = new FileStream(Server.MapPath("~/ReleaseNotes/" + filename), FileMode.Open, FileAccess.Read, FileShare.ReadWrite);
                long FileSize;
                FileSize = sourceFile.Length;
                if (sourceFile.Length > 0)
                {
                    byte[] getContent = new byte[(int)FileSize];

                    sourceFile.Read(getContent, 0, (int)sourceFile.Length);
                    sourceFile.Close();
                    Response.BinaryWrite(getContent);
                }
                else
                {
                    Response.Write("File is Empty");
                }

                Response.End();
            }
        }
        catch (Exception ex)
        {
            Response.End();
        }



    }

I opened that TextFile.aspx page from code behind of some other page by writing the code something like this:
ClientScript.RegisterStartupScript(typeof(Page), "ErrorOccurred", "<script type='text/javascript'>window.open('ReleaseNotes/TextFile.aspx')</script>");
