Hi Elizabeth Zeller,

Thank you for sharing such a detailed explanation — it really helps to understand where things stand. You’ve already taken some great steps by installing QuickBooks Desktop Enterprise 2024 on your main office computer, entering your license information correctly, and confirming that all three PCs are connected to the same network. That’s a strong start, and you’re actually well on your way to enabling multi-user access.

Since you’ve run into installation issues on the other two computers and trouble connecting to the shared company file, there are just a few more key things to check and adjust. These include properly setting up hosting roles, sharing the company file folder with the right permissions, and making sure QuickBooks Database Server Manager is installed and running on the main PC only. With a little fine-tuning on these parts, you’ll be able to get all three systems working seamlessly together in a multi-user environment.

Important:

• QuickBooks Desktop 2024 uses the QuickBooksDB34 service to manage company file access.
• QuickBooks Desktop Enterprise supports up to 30 users working in the same file at once.

Why Multi-User Setup Fails in QuickBooks Desktop Enterprise 2024?

Multi-user access can be restricted due to network misconfigurations, wrong firewall settings, or improperly assigned hosting roles between computers. There are a few common reasons why you’re getting trouble when setting up multi-user mode in QB Desktop Enterprise 2024.

1. Hosting is turned on/off incorrectly on one or more PCs. 
2. The company file is not stored in a properly shared folder.
3. QuickBooks Database Server Manager is not installed or running on the main PC. 
4. Firewall or antivirus is blocking QuickBooks connections. 
5. All PCs are not on the same local network. 
6. Wrong installation type selected during setup on workstations. 
7. A Network drive to the shared folder is not mapped correctly. 
8. The file is not opened in multi-user mode from the host computer. 
9. Insufficient QuickBooks user licenses for simultaneous access. 
10. Windows file permissions are not properly configured to allow shared access.

Step-by-Step Guide to Setting up Multi-User Mode in QuickBooks Desktop Enterprise 2024 On Different Computers

Setting up multi-user mode in QuickBooks Desktop Enterprise 2024 allows multiple users to work on the same company file at the same time. If you’re working on two or more computers, make sure that the QuickBooks is installed on all the systems but the QB Database server manager should be installed only on the Host PC where the company file is stored.

Method 1: Download & Install QuickBooks Desktop

These steps are used to install QuickBooks on either a dedicated server or computers that access the data on a server. This can also be a Terminal server or a server that hosts both QuickBooks and your company file. When you access your company file from a server, make sure to use the direct path to your company file.

1. Make sure you have an active internet connection.
2. Open the file QuickBooks.exe.
3. Choose Custom and Network Options and then click Next.
4. Select the following:
   • I’ll be using QuickBooks Desktop on this computer to install on a workstation.
   • I’ll be using QuickBooks Desktop on this computer AND I’ll be storing our company file here so it can be shared over our network to install QuickBooks on a server and host files on the same computer. You can use this option to install on a Terminal Server.
   • I will NOT be using QuickBooks on this computer. I will be storing our company file here so it can be shared over our network to install only the QuickBooks Database Manager on a server to host files.
5. Click Next.
6. Select Next to start the installation.
7. To change the installation location, select Change the install location then Browse to decide where to keep your QuickBooks folder. Most people put it in their Programs folder.
8. When finished, click Open QuickBooks.

After the installation, QuickBooks will ask you to activate and update it.

Method 2: Install QuickBooks Database Server Manager

Install QuickBooks Database Server Manager on the server computer — the one where your company files are stored and shared.

Recommendation: If you’re an accountant or someone who hosts multiple versions of QuickBooks Desktop on your network, install them in order. Install the oldest version first and end with the most recent.

1. Close all open programs on your server computer, including QuickBooks.
2. Open the install file you downloaded. It’s called Setup_QuickBooks.exe.
3. Follow the on-screen instructions. 
4. When QuickBooks asks you to choose an install type, select Custom or Network Options. Then, click Next. Don’t choose Express.
   • Note: The Express option installs QuickBooks Desktop over your previous version of QuickBooks Desktop and you might need your previous version for comparison and troubleshooting purposes.
5. Choose the best option for your network setup and click Next. Both options install the Database Server Manager. If QuickBooks Desktop is already installed on your server computer, this won’t overwrite any existing company data.
   • Select I’ll be using QuickBooks Desktop on this computer, AND I’ll be storing our company file here so it can be shared over our network if you want Database Server Manager and QuickBooks Desktop on your server computer.
   • Select I will NOT be using QuickBooks Desktop on this computer if you only want Database Server Manager on your server computer.
6. Follow the rest of the on-screen instructions.
7. Once done, select Install. Windows may ask you for permission.

Note: QuickBooks creates a new Windows user for each version of Database Server Manager. For instance, Database Server Manager 2023 shows up as QBDataServiceUser33.

Give QBDataServiceUserXX (where XX represents the QuickBooks version number) permission to access the folders that hold your company files. You may see these users whenever you set system-level permissions and it is essential for multi-user functionality.

Method 3: Set Folder and Windows Access Permissions

When setting up multi-user in Quickbooks Desktop, save your company files on your server computer’s local hard drive. This makes it easier to share them over your network. Check the folder permissions on your server computer, so we can make sure that the folder holding your company files has permission to be on your network.

1. Hit a right-click on the folder storing the company file.
2. Navigate to Properties.
3. Select Security and Edit.
4. Choose QBDataServiceUserXX and click Full Control.
5. Press Allow.
6. Click Apply, and hit the OK button.

When you’re ready, follow these instructions below:

1. Hold and Press Windows + E keys to open File Explorer.
2. Locate and right-click on the folder containing your company files.
3. Go to Properties > Sharing > Shared Add.
4. Select the corresponding QBDataServiceUserXX for your version.
5. Set the permission level to Full Control for both users and click Share.

Method 4: Enable Hosting On Multi-user Mode

Enable the Hosting only on the host computer to give other systems access to your QuickBooks company file and it should always be connected when others need access.

1. Navigate to the File menu in your QuickBooks Desktop.
2. Choose Utilities.
3. Select Host Multi-User Access.

4. Click Yes.

Method 5: Map a Network Drive in Windows

For Windows 11:

1. On your keyboard, press the Windows icon.
2. Enter This PC in the search bar. From the search results, choose This PC.
3. Select More (…) then select Map network drive.

   • enter only the path to the computer the file is hosted form and select Browse to find the folder
6. Select Reconnect at sign-in to keep the drive mapped every time you sign in to your computer.
7. Select Finish.

For Windows 10:

1. On your keyboard, press the Windows icon.
2. Type This PC in the search bar. From the search results, choose This PC.
3. Under the Computer tab, select Map a network drive.
4. Select any unused drive letter then select Browse.
5. Go to the network location where your QuickBooks company file is stored.
   • (Note: If you’re having trouble mapping the network drive using the UNC, try using the IP address of the server.)
6. Select OK then Finish.
7. Reopen your QuickBooks company file from the new mapped drive.

Method 6: Check the Network Connectivity

1. Hold and Press Windows + R, type // [Host (Computer Name], and click Enter.
2. Replace [HostComputerName] with the name of your host computer.
3. Verify both computers are on the same network in case it doesn’t open.
4. Locate the folder with your QuickBooks company file and confirm access.

Method 7: Open Company File in Multi-User Mode Automatically

There are two ways to open company files in Multi-user mode automatically. The first one is to check the Open file in the multi-user mode option.

1. Go to the File menu.
2. Choose Open or Restore Company.
3. Select Open a company file, and click Next.
4. On the Open a Company window, check the Open file in multi-user mode box at the bottom.

Each time you open the company file from the computer, the multi-user mode will be enabled. You can do this on every workstation.

The second one is to edit the QBWUSER.INI file and then change the MULTIUSERMODE value.

1. Navigate to the AppData folder. The default location is: C:\Users\(username)\AppData\Local\Intuit\(Your QuickBooks Desktop version)
2. Locate QBWUSER.INI and open it using Notepad. 
3. Press CTRL + F and find MULTIUSERMODE.
4. Change the value to “Y” (MULTIUSERMODE=Y). 
5. Once done, save the file.

When the system reverts the file to the original value, do this:

1. Hit right-click on the QBWUSER.INI file. 
2. Select Properties. 
3. Hit the General tab.
4. Check the Read-only box.
5. Click Apply, and Save.
