Thanks Tim Still too old fashioned I guess - Sometimes I just want an earthly being to answer my question :-)
Yes so the cmd line syntax is nircmd.exe win close class "CabinetWClass" Which closes all explorer windows. (not ideal) so there is another more specific syntax: nircmd.exe win close title "MyAppFolder" That is really it. As you said a copy of the nircmd should be included in the resources folder. Set path name to it and LEP. Very neat. Thanks for the tips. Now I need to see how this update process works on a Mac. There are some apple scripts that close finder windows. But will get there when I get there...
