Issue in Conversion from Access 2007 to Access 2016

[cstimart]

I'm testing my VBA code(s) for a conversion from 2007 to 2016. All seems to work well, except for the following:

My Access db opens Excel creates a document/tab and also tries to Freeze the top row of each sheet. The code works perfectly in 2007, but in 2016 I get an error that says 'Unable to set the FreezePanes Property of the Window class.'

With xlApp.ActiveWindow
    .SplitColumn = 0
    .SplitRow = 1
    .FreezePanes = True
End With

When debugging, I hover over .FreezePanes and the current value is False.

Any idea(s) why?
