Excel Process is not terminated when using C# and com Interrop
 

How do you stop the Excel proces from running the following code works on some boxes but not others.It seems that it is impossible to terminate the Excel process.

if(ws != null)
{
System.Runtime.InteropServices.Marshal.ReleaseComO bject(ws);
ws = null;
}
if(wb != null)
{
for(int i = 1 ;i < wb.Sheets.Count; i++)
{
((Excel.Worksheet)wb.Sheets[i]).Delete();
}

System.Runtime.InteropServices.Marshal.ReleaseComO bject(wb);
wb = null;
}

if(excelApp != null)
{
excelApp.Quit();
System.Runtime.InteropServices.Marshal.ReleaseComO bject(excelApp);
excelApp = null;
}

System.GC.Collect();

It is not possible for me to use process.kill because the web based application that this used with ddoes not issue admin rights to its users.
