Good afternoon,
I'm a Desktop Support Specialist; currently, my company is upgrading users to Office 2016, and one of our departments uses PowerPivot. They've attempted to convert a PowerPivot spreadsheet made in Excel 2010 to 2016, but ran into issues. I took it upon myself to help (without any knowledge of PowerPivot, I'm afraid), but I can't seem to figure it out. I've searched online in many places, but all came to dead ends.
Here are the steps of the issue:
-Installed three PowerPivot patches found at https://support.microsoft.com/en-us/kb/3114297 (Otherwise PowerPivot won't start)
-Opened the spreadsheet in Excel 2016. A message appears saying that an older version of PowerPivot was used, followed by another message asking the user if they want to upgrade the spreadsheet. Clicked "OK".
-Another message appeared, stating that the spreadsheet needed to be saved, closed, and reopened . Clicked "OK"
-Error appeared, stating workbook can't be saved.
-If re-attempted, another error appeared:

Error Message:

Can anyone please help?
Thank you,
