If you are installing (or reinstalling) an older version you will have to update it. Quicken does not have the updates for the older programs but One of the SuperUsers has posted the update patches for older versions (2000 and newer) of Quickenhttp://www.quicknperlwiz.com/quickenpatches.html

How Do I Move Quicken Data Files Between Computers

ssf said: I have Quicken 2015 Deluxe, which no longer works, apparently because I installed it on a new computer so I need a new ID. This is annoying (if true) because I thought I bought a perpetual license. Anyway, I now want the cheapest way to use my Quicken database on the new computer. It seems that I must buy a subscription. If that's correct, can I use a Starter subscription or must I buy Deluxe, to match my existing Deluxe license?
ssf said: So my question is, can we use the live database on both machines now? If not, what should we use? Since that database has been working on my computer, I can't see why it wouldn't work on both of them. However, I'm concerned by Quicken's warning. Thanks again.We've had 2 users, each with their own computer, sharing a Quicken database for years. I know that that's not supported, but it's been working. The users don't use Quicken simultaneously. We have good backups and would be satisfied to rely on them if necessary, but so far haven't had to do that.
