How get current path of exe in windows services

Hi,
 I am using windows serives. I have one windows application. Now i call the exe of this application in windows service using System.Diagnostic.Process.Start(exepath). It is working fine. But i have the problem that in windows application i get the values from ini file using current directory path that Application.startupPath(exename).

I can get the values from ini file when run windows app alone. But i put the exe to services i can't get the value. Because the current directory path shows in services that C://Windows/System32. So i put the ini file in the path. It is working fine when run the services and get the values.

But i dont want to do that every time put the file in the system32 path. I put the file in windows service path when create setup. so i want to get the values from the services directory path. How can we achieve this scenario? I believe that you catch my point that what i am telling here. Hope expecting your reply.

Thanks
