zip.tempfilefolder = configurations.appdatapath; but doesn't seem fix problem.
kindly , let me know
you can download file temporary location, using path.gettemppath() (msdn). after download complete, can move file file.copy(...) user's folder , delete file temp file.delete(...).
using approach won't acces denied exception.
