A:Answer You are able to install Quicken on multiple computers. However, you can only access one data file at one time and the data file is local to one computer, you cannot update a data file simultaneously by more than one computer example on a network. So in short, it is best to pick one main computer which you use the most often and then have that data file there. If you would like to make simple updates or get some data, then use the Quicken app (iOS, Android, and Web app) to access the data through the cloud. The web app especially is quite good and meets my needs.
