I'd be glad to help you download the 2012 version of QuickBooks Desktop, @Volunteer50.

After that, make sure to restore the file in between versions to avoid file damage.
- Install QuickBooks Desktop in your new computer.
- Create a backup company file on your original computer.
- Save the backup file somewhere you can easily find it and give a unique name so it's simply to identify.
- Move the backup company file to your new computer.
- Follow the steps to restore the backup on your new computer.
- If you use payroll, download the latest tax table after you move your file.
Once transferred, let's start to upgrade your company file. Here's how:
- Make sure all users are logged out of your company file.
- Open your new version of QuickBooks Desktop.
- Go to the File menu and select Open or Restore Company.
- Click Restore a backup copy and then click Local backup.
- Browse your computer for your company file. You wrote down the file location in Step 1. Select it and then click Open.
- Sign in to your company file as an admin user.
- Before you upgrade, QuickBooks automatically creates a backup of your existing company file. You can select Change this default location to save the backup in a specific folder.
- Choose Update Now to start the upgrade.
- Click Done.
Once done, you can now open your existing company file in your new version of QuickBooks Desktop.
Additionally, you can refer to this article to update QuickBooks to the latest software release: Update QuickBooks Desktop.
