I have tried to enable the Analysis Toolpak in Excel. It has been checked, but I am not getting it in the Data tab. I've tried unchecking it and rechecking it, but nothing happens. I've tried unchecking it, closing Excel, reopening it, and rechecking it. I've tried uninstalling and reinstalling Office 365. I've checked that the add-ins are not blocked in the Trust Center. I've been spending several hours a day for a few days researching this problem and following the advice but still cannot figure this out. Please help!
