Locate program path

OK... with a little more research I found my answer -------------------------------- using Microsoft.Win32; string myPath = ""; RegistryKey rk = Registry.LocalMachine.OpenSubKey("SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\App Paths\\SomeProg.exe", false); if(rk != null) { myPath = rk.GetValue("").ToString(); } ------------------------------------ In the code above I am getting the "Default" value which contains the programs executable path. The "false" parameter says that I want to open the key as read-only. I am not sure if the rk != null check is the right way to check that the key existed, but at first test this appears to work.
