Solution 1

Move the Process.Start instructions from the Form.Load event to the Form constructor - you could also hold your constructor from completing until the other apps are running, by check calling Process.GetProcessByName and ensuring they are all there.

Solution 2

Depending on the processes you are starting you might be able to do something like this

System.Diagnostics.Process proc = System.Diagnostics.Process.Start("name.exe");
proc.WaitForInputIdle();

There is also an overload for WaitForInputIdle(int timeout) so it will only wait so long and then return.

still form load event is complete before exe start.

Ok, the WaitForInputIdle only works if the exe has a GUI or message pump. Probably the best bet is to have a controlled loop and perform the method from solution 1 above.
