Re: How to execute a DOS command?

OK, by "dos" I am assuming you mean cmd?  (Unless you mean the no longer supported command.com which was executed in 16 bit mode up to XP, I think.) 

 In any event, I don't know much about the command lines of either, but someone once suggested a cmd line like this to run a powerpro restart after a delay; perhaps something similar will work for you: (The ping stuff has the delay):
 

 cmd /k ping -n 4 127.0.0.1 > nul && start "" "C:\Program Files (x86)\PowerPro\Powerpro.exe" C:\Users\userid\AppData\Roaming\PowerPro\pproconf.pcf && exit
