Good day, fclopena.
When your application has reached 3 years, the only way to update it is through upgrading your QuickBooks to the latest version.
QuickBooks Desktop has a 3 year discontinuation policy. This means that if you have QuickBooks 2015, it will discontinue in 2018. Before we discontinue your application, we will notify you in advance through the mail, email, in-product notifications, and this Community page.
Once updated, make sure you enter your latest company details.
If you have questions about our discontinuation policy, don't hesitate to reach out to me.
