I am having the same issue. QB Desktop 2019. Microsoft Office Professional 2010 32-bit.  Use this same set up on other computers in our office with no issue. I have gone through all of the steps here: https://quickbooks.intuit.com/learn-support/en-us/run-reports/fix-export-to-excel-issues-in-quickboo... with nothing working.  I called to talk to Support which they say that it is a "rare situation" and it must be an issue with Microsoft Office.  Looking at this thread, it is not rare.  What am I missing? Help.
