Why don't you make a new vi which contains a sequence structure and their you put in the program you want to run first (inserting a sub.vi) and then a pause or the second program and so on.
I attached a screenshot by which i think you want to have your program.
If you want to open other executables (for example ms exel and after few seconds open ms word) then its also possible to use the sequence structure.
I hope i understand the question correctly, and this will help you solve your problem
