I know this question has been asked many times but the search function of EE does not work worth a hill of beans so I will use my points to ask this question again.

How do I start another exe and kill the current exe. My application checks a folder on the network for an updated exe. If the version numbers don't match I want to copy the new one locally. This is not the problem. I am having problems starting the copy exe and then starting the application again.
All I need is the best code to start another exe and kill the current program. It needs to work on both Win95/98 and W2k Pro.

You don't need any fancy stuff to remotely kill no process.
Let your program check the versions itself. On new version detected, run the new version with some switch, telling it to perform the upgrade and make the running one end properly. The new version should (upon receival of the switch) wait for any instance of the caller to end, copy itself over the caller then invoke the (updated) caller without switches and terminate silently. This will surely work on any OS.

I'd use CreateProcess.

var
  StartInfo : _STARTUPINFOA;
  ProcessInfo : _PROCESS_INFORMATION;


GetStartupInfo(StartInfo);
CreateProcess('*.exe', pchar('Command Line to execute'),
 nil,nil,false,CREATE_NEW_CONSOLE,nil,nil,StartInfo,
 ProcessInfo);

I would agree with YodaMage; when I implemented this trick I used CreateProcess, too, but there are also other ways that could work. Stick with what seems more familiar to you.
