[mod note: moved installation forum iis installation forum; ]
to you, in future, find correct forum topic please read which forum post question have put together.

you seemed have missed point - please run fpa in joomla_root/ directory wherever joomla installed.

that said clear you in fact installing on windows iis php, other factors clear system tmp/ directory unwriteable, far relevant/useful information goes!
