Hi,

Was this error pop-up when opened an Excel file in local disk? As far as I know, the 0x800A01A8 error "Object required" is roughly equivalent to an invalid pointer exception you might want to check all the argument you are passing to Excel.

I suppose this issue might be cased by some Excel Add-in (Third-party VSTO add-in), please try to disable all the add-ins and check if it is helpful.
