I have family lawyer on Windows XP, but can no longer open the files to update/change my will and trust. If I download the latest version, will it work on both Windows XP and Windows 7 or 10?
The latest version of Quicken is available for opening on Windows 10, but you will have to use an intermediate version to migrate the data so that you can open it in the latest version.
Luckily, Quicken published a support page where you can see how to do that. Use the following link to obtain additional information: http://www.quicken.com/support/how-and-when-use-intermediate-version-convert-older-versions-quicken
