Well because there are so many different flavors your best bet would be to create a very generic query. Don't forget to update the column view with the application suite name to help you see what is listed, and then allows you to modify an exported list.
"Computer"."Software"."Application Suites"."Application Suite"."Name" Like "Microsoft Office"
Awesome! One more step: Can we get totals out of this?
That I am not sure, but what I do, is use the query to create a report, then I export the report to a Excel or CSV file and do the rest (the count) manually.
