Hi there, Dholley328. 

I appreciate you posting your concern regarding upgrading your QuickBooks Desktop (QBDT) and unable to reinstall your subscriptions. Let me share another way to install your QBDT on your computer.

As you mentioned that you previously attempted to install the latest software using QuickBooks Desktop Manager, I would like to suggest an alternative option that could be helpful in your case. Lightworks is a cloud-enabled version of QuickBooks Desktop that allows you and your team to work online and remotely.

Here's how to use Lightworks:

1. Log into Rightworks My account using your email address and password.
2. Select Users, then choose the specific user you want to apply for the license.
3. Within the user detail page, select Apps you can install. Rightworks displays all QuickBooks versions available to you. To locate the version, use the search button.
4. Click the correct QuickBooks version, then select Install. Follow the prompt that appears. Then, a shortcut will be displayed on your desktop.

You can utilize this article to know how to upgrade your QBDT: Upgrade QuickBooks Desktop Pro Plus, Premier Plus, or Enterprise.

Furthermore, I recommend contacting our QuickBooks Support team if the issue persists. They'll look into this matter with their tools and find an adequate solution.
