Yes, you're correct, @JoshRountree.
You have to make sure that QuickBooks Desktop is downloaded on the server's computer. In step 1, you will only select I will NOT be using QuickBooks Desktop on this computer if you just want your server computer to host your files. This option does not allow you to work on QuickBooks from the server computer. Then, follow the on-screen process to install the QBDT.
This way, you'll be able to turn on the Multi-user Access on your server computer in step 7.
For more details, please refer to this article: Set up and install a multi-user network for QuickBooks Desktop.
Here's a great source you can read that provides detailed information on QuickBooks Desktop hosting and multi-user mode: Hosting your company data in multi-user mode in QuickBooks Desktop.
Keep me posted if you have any other concerns about setting up multi-user in QuickBooks. I'm always here to help. Have a great day ahead.
