I am running Windows 10. I have Office 365 ProPlus with 2013 apps installed on my laptop.
A few months ago, Excel started opening up a "PERSONAL.XLSB" file every time I opened the program. It didn't happen before. Looking online, one solution was to hide the file. I did this by creating an "Archive" subfolder in the ...\AppData\Roaming\Microsoft\Excel\XLSTART
folder that the personal.xlsb file was saved in and stashing the file into the "Archive" subfolder.
Around the same time, the following error started to pop up when I open up Excel:

The error doesn't come up everytime. It seems to come up every other time I open Excel. I know all is not right with the software because when I close the program, the program flickers through another window. Otherwise, Excel seems to run fine for what I
use it for (minor spreadsheet work).
I'm not sure if this issue is related to the PERSONAL.XLSB file issue or not, but I wanted to bring this up to provide as much information as possible.
I have gone twice through the following complete cycle: uninstalled Microsoft Office, shut down the computer, and reinstalled Microsoft Office. The error has not gone away.
Can someone help me get rid of this error every time I open Excel?
