One of our machines is running Office 2016 on Windows 7. The personal.xlsb file does not open when an instance of Excel is opened. I have deleted the original persona.xlsb file and then recorded a new macro to the personal.xlsb file in order to make a new one via the newly installed Excel 2016. Even after this was done the personal file doesn't open. The folder location IS listed in Trusted Locations. Any idea why this is not opening as it should?
