According to the Quickbooks PRO 2006 FAQ, it is acceptable to install the single user version on up to 20 machines, as long as only copy is used at a time.
My question has to do with the one time free tax table download. If the quickbooks is installed on 2 or 3 machines, is it possible for them to all get the free download?
I seem to recall this question from years ago, but I can't find the record of it. I thought someone said that it was possible to do multiple downloads using the one license during a specific time window, like 24 hours, although my memory of this is not vivid and I may be confusing Quickbooks with some other product.
