You can install QuickBooks Desktop (QBDT) 2019 on your laptop and restore the company file shared on the network. 

Before doing so, make sure your company file has a multi-user feature is turned on. You can have this article as your reference on how to do so: Set up and install a multi-user network for QuickBooks Desktop.

You can also use sa QBDT installed on your host computer where the company file is stored.

Keep me posted for additional questions or other concerns. I'd be more than happy to help. Wishing you the best of luck.
