Important Notice for Mac Office 2016 users. In August 2016, Microsoft updated its recommended version of Excel 2016 for Mac to a 64-bit version. This update renders many Excel add-ins inoperable. The recommended solution is to revert to the 32-bit version of Excel 2016 for Mac as documented by Microsoft here. You are looking for the Office 2016 for Mac 15.25.1 32-bit (legacy compatibility) option for Excel, which is at of 8/29/2016: DownloadDownload the Excel package now

Is APEx not loading when you restart Excel after installation? Recent updates to Microsoft Office require that you make the folder in which you install APEx a "Trusted Location". To fix this, go to the File tab, then select Options. Now select Trust Center from the sidebar. Click the Trust Center Settings button, then select Trusted Locations from the sidebar. If you have placed APEx.xlam anyplace but one of the list locations, click Add new location. Click Browse and navigate to the location where APEx.xlam is saved. Click OK four times to exit and restart Excel. If APEx is installed, it should now load.
