QB Issue Resolution:

Yes, you can safely uninstall the 2015 version since you’ve already converted it into the new 2019 format. Before performing it, I recommend saving a backup copy of your old file on a flash drive in case you need it for future reference.


Here’s how:


  1. Go to the Windows Start Menu on your computer.
  2. In the Search box, enter Control Panel and open it.
  3. Select Programs and Features or Uninstall a Program.
  4. Choose QuickBooks Desktop 2015 in the list of installed programs.
  5. Click Uninstall/Change.
