Sadly, your response is a little unclear to me. Are you saying if you had Money 99 you could make it into a portable app? If that is the case I am certain I can get it to you somehow.
Or, are you stating you simply can't make it portable?
I have used Money 99 for 26 years of business records and I like it. I would look invaluable records if I quite using it. I can use it on Windows xp, 7 and 8.1. Can't use on Win 10.
Can it be made into an app that word work on Win 10? Perhaps that is an unknown.
