SPC for Excel Version 6 is distributed in a zip file for both PC and Mac. The same file works on both the PC and the Mac. The zip file is downloaded when you select the link emailed to you after you purchased the software. This link can only be used once and expires after that. Sign into your account after that to download the software. The name of the zip file is “SPC_for_Excel_V6.zip.

Earlier versions of SPC for Excel will be uninstalled as add-ins when Version 6 is installed. If you want to uninstall the earlier versions completely, please see the instructions below (To Uninstall Previous Versions).
