Hello there, vsilinin. Let me share some information about providing access to the company files remotely with QuickBooks Desktop Premier 2017 (QBDT).
To provide access to the other user with the company files remotely, you'll need to use QuickBooks Premier Hosting Features that allow greater control over your information anywhere, and it could be costly but more convenient.
Here's an article you can refer to see what companies are authorized to host QuickBooks and see other information with hosting setup and installation: Hosting providers authorized by Intuit.
For the system requirements for QBDT Premier of 2017, you're correct. They can't install it to the Windows 11 Operating system (OS) since this is not a supported OS version, and it could trigger errors. Let's ensure their computer or laptop hardware, software, and OS meet the minimum requirements for your version of QBDT.
Furthermore, you can check out this article to learn how to manage your accounts, products, contacts, billing, and user ID access: Change, manage, or update your Intuit account with CAMPs.
