Hello @Robert Petrie
Thank you for reaching out on the community and telling us about your issue. You're able to download the subscription version of quicken on as many computers as you like. Here is an article that goes more in depth on the topic as well. Here's also another one to download quicken onto your second computer. If you're able to grab a backup or file from a flash drive you'll still be able to continue using that file on your second computer for the time being as well.
Please let us know if this helps resolve the issue for you.
Thanks,
Quicken Francisco
