Error: "Macro may not be available or all macros be disabled"

This is a rare issue and is due to Excel permissions.

Solution:

1.  If using a 64-bit version of Excel, move the Statement Converter .xla file to the 32-bit folder.  For example:

instead of:   C:\Program Files\Microsoft Office\Office15

install in:  C:\Program Files (x86)\Microsoft Office\Office15

and then add the new folder as a "Trusted Location" in the Trust Center:

Excel 2013 > Options > Trust Center > Trusted Locations > Add location

(in the Description field, you may optionally want to note "for Statement Converter")

2.  Ensure that Excel allows macros to be run:

Excel 2013 > Options > Trust Center > Macro Settings > checkmark "Enable all macros"
