I am trying to get it to skip the bottom command if the file at the begining is there.

the line ;do nothign is my problem. if it finds file xx.exe it shoudl skip to the next set of commands and not install the patch. if i replace ;do nothing? with quit it quits the script adn doe snot run the rest. I want it to install a patch only if it is on windows xp pro with sp2 and only if it hasnt already been installed.
