My updater is failing to close my main program (C#) -

-

i have updater, called via main program once update detected (from remote xml file), first checks whether process open

if (clsprocess.processname.tolower().contains("conkinator-bot.exe")) {      clsprocess.closemainwindow();     return true;  }

(this gets run every process until finds (foreach loop))

the updater downloads file: 

client.downloadfile(url, "conkinator-bot-new.exe");

and attempts delete current 1 , rename it: 

file.delete("conkinator-bot.exe"); file.move("conkinator-bot-new.exe", "conkinator-bot.exe");

but error when occurs following:

unhandled exception: system.unauthorizedaccessexception: access path 'd:\conkinator's skype tool\conkinator-bot.exe' denied.

however new version of program download.

just because main window closed doesn't mean process over. need wait process exit after close main window:

clsprocess.waitforexit();

ideally, you'd use timeout - there might preventing window closing, or process might have faulty exit mechanism.
