Intuit will support QB Desktop 2024 until May 2027 as long as you pay the renewal fee. You will need to contact the new owner of the company so you can transfer Primary Contact access.

Otherwise you may have 2 options:

1. Purchase another QB Desktop 2024 Pro Plus license to access your company file.

2. If you don't need to use any add-ons, switch to old QB Desktop with a non subscription license.
