If so, where can I download it? An MSI file is needed for Excel PTS services on a Windows machine, which we use. However, we have a MAC user that is stating that they cannot use the dropdown functionality in Excel for our Pivot tables, I dont have a test MAC machine so I wasnt able to test this. I'm assuming there's a PTS package (MSI file) needed for a MAC where can I find this? I'm searching Microsofts website but havent found it yet. Any help would be appreciated THANKS!!!
