I don’t know how to open the ZIP attachment

Your kit may contain from 10 to over 30 different files, so we zip them all into a single attachment. Zip files are compressed and smaller to email, making it easier for you to save, forward and print. This file has the extension ".zip". Almost all computers include an unzipping program. Double-click or right-click the zip attachment and chose to extract or save the file to your desktop or another known location on your computer.

Don’t have unzipping software? Download zipeg (always free) or a trial version of Winzip.
