We may install the Quicken program on as many computers as we'd like.
To install Quicken on the new computer, I suggest you download and
open:
https://download.quicken.com/windows/Quicken.exe
If you want to access the same Quicken file, I suggest you also copy
the Quicken file from the old computer to a folder on a local drive on
the new computer.
There are many ways to copy files between computers. For example, you
may use a thumb drive.
