Another approach might be to start Excel as an automated instance, which
means no startup workbooks will load, not even addin workbooks. You could do
that from an already running instance of Excel, or from a simple vbs script,
eg
with createobject("excel.application")
..visible = true
..workbooks.add
end with
from a text editor like Notepad save as say "EmptyExcel.vbs"
FWIW, unlike starting in safe mode, this way would start Excel with full
customized toolbars
