  • Database Server Manager crashes instantly if it cannot access the company file from its location due to insufficient folder permissions.

  • QuickBooks temporary rebuild files (.qbt) incur damage due to data corruption in your HDD.
  • Database Server Manager issues become common if the hosting settings aren’t correctly configured on your QuickBooks.
  • QuickBooksDBXX service cannot run due to damaged DBSM files or misconfigured settings on your system.

Viable Methods to Prevent Error 193: 0xc1 while Trying to Open QuickBooks

Now, after knowing the root causes of QuickBooks error 193 0xc1 preventing you from opening the software in multi-user mode, you can proceed to learn about the methods you need to counter the issue. We have accumulated the most reliable and effective techniques you must use on your system. Check them after ensuring the assumptions we made are correct-


  • You aren’t using Database Server Manager on Network Attached Storage (NAS) devices.
  • You are signed in as an Administrator to your Windows.
  • You have already consulted the customer support team of thirdparty hosting providers (if you use any) like AbacusNext, Proxios, MyVao, etc.
  • You have the latest QuickBooks Desktop on your system.

Method 1- Configure the Windows Firewall Port settings manually

Windows Firewall and other security programs pose a major threat to QuickBooks if their settings aren’t correctly configured. The software might be completely blocked from accessing the internet, connecting to other systems, or running the system files. The first step you must take is to access the antivirus settings and go through the blacklisted/quarantined programs or files. Ensure that QB files like QBDBMgrN.exe, QBDBMgr.exe, QBW32.exe, etc, aren’t in the list, or remove them if you find any. The second step is to configure the Windows Firewall settings and add new ports for QuickBooks, as shown in the following steps-

Exclude QuickBooks from Windows Firewall
Configure Firewall Ports
  1. Press Windows+R on the keyboard to launch the Run command on your system.
  2. Type ‘control’ in the text section and click Ok to open the control panel.
  3. Click the View By option and select Small icons.
  4. Tap the Windows Firewall option and move to the Advanced settings tab in its window.
  5. Right-click Inbound Rules and select the New Rule
  6. Click Port and hit Next to go to the next window, where you need to select TCP.
  7. Go to the Specific Local Ports section and fill in the Firewall ports using the list below-
    • QuickBooks 2017: 8019, 56727, 55373-55377.
    • QuickBooks 2018: 8019, 56728, 55378-55382.
    • QuickBooks 2019: 8019, XXXXX.
    • QuickBooks 2020 and later: 8019, XXXX.
  8. Enter the Firewall ports correctly and click Next after you’re done.
  9. Tap Allow the connection option and move to the next window by clicking Next.
  10. Ensure all your user accounts are selected before clicking Next.
  11. Create a new rule with any preferable name and click Finish.
  12. Repeat all these steps after selecting Outbound Rules instead of Inbound Rules in step 5.

We advise you to create exceptions in the Windows Firewall settings for QuickBooks files and programs. This can be easily done using the following steps-

  1. Go to the Inbound Rules option in the Advanced Settings tab again (Windows Firewall settings).
  2. Click the Program option and tap Next.
  3. Choose the This Program Path option and click Browse.
  4. Select DBManager.exe, QBDBMgrN.exe, QBLaunch.exe, and all the other QB executable files from C:\ProgramFiles\Intuit\QuickBooks20XX.
  5. Single-click Allow the connection and hit Next.
  6. Mark all the user accounts in the next window and assign any name to the rule you create.
  7. Select Outbound Rules in place of Inbound Rules in Step 1 and perform all the steps again.
  8. Reboot your system.

Note: Your program files folder name will include (x86) if you use a 64-bit OS.

Applying the steps mentioned above configures the Windows Firewall Settings in favour of QuickBooks and you don’t have to worry about your accounting software getting blocked again. In case your QuickBooks encounters error 193:0xc1 again during launch, we suggest you move to the next solution.

Method 2- Recreate corrupt/damaged Transaction log (.tlg) and Network Descriptor (.nd) files

Transaction Log file is an exact replica of the company file used to check for discrepancies in financial transactions while hosting the data file. Meanwhile, the Network Descriptor file contributes to assisting the Database Server Manager in locating the data source and paths to all the workstations. These files are critical for DBSM, and its failure to access them causes problems sharing the data file or launching QB in multi-user mode. You can easily resolve the issue by recreating the damaged files to ensure DBSM runs smoothly in the future. Refer to these steps-

Modify the Names of the .TLG & .ND Files
Modify the Names of the .TLG & .ND Files
  1. Open the file explorer and go to C:\Users\Public\Public Documents\Intuit\QuickBooks\Company Files.
  2. Look for files with extensions .nd, .tlg, .dsn and right-click each individually.
  3. Select the Rename option in the list and add ‘.old’ as an extension at the end of the file name.
  4. Try opening DBSM separately and navigate to the Scan Folders if it opens.
  5. Hit Browse and enter the location where you recreated the QB files.
  6. Clicking Start Scan registers the folder contents on the network and reopen QB after the scan is complete.

Database Server Manager can access the program files easily after they are recreated using the steps given above. If the same error reappears during the software launch, you must move to the next solution.

Method 3- Configure the folder permissions of the data file folder

Whenever you host the company file in QuickBooks, the Database Server Manager scans the data file and makes it accessible to all the other workstations. In case you use a non-admin Windows account or the folder permissions of the data file folder aren’t correctly set, QuickBooks faces problems accessing the company file. This makes the company file inaccessible, and QB faces instant issues when insufficient folder permissions stop it from connecting to the data file. You must configure the folder permissions using the following steps to prevent issues while connecting with the data file-

Ensure the Folder Permissions are Set Correctly
Verify the Folder Permissions Manually
  1. Use the file explorer to visit C:\Users\Public\Public Documents\Intuit\QuickBooks\Company Files.
  2. Right-click the data file folder and select Properties.
  3. Go to the Security tab and select QBDataServiceUserXX from the account list.
  4. Tap Edit and mark the Full Control option with a single click.
  5. Click the Apply option to save the settings and reopen QuickBooks after closing the Properties

After the folder permissions are set up correctly, you must enable folder sharing to make the company file folder accessible to all the user accounts. Here’s how-

  1. Right-click the data file folder and select the Properties
  2. Go to the Sharing tab and click the Share this folder
  3. Move to the Security tab and allow all the permissions to every Windows account.

Database Server Manager won’t face any restrictions after the company file folder permissions are configured. We advise you to sign in with the Windows Admin account to prevent restrictions while accessing the system files or acquiring its resources. If QuickBooks error code 193 0xc1 appears again when opening the software, jump to the next solution immediately.

Method 4- Repair Database Server Manager and recreate the QBDataServiceUserXX account

QuickBooks DBSM can also suffer issues if its settings aren’t properly configured on your system or the program files are damaged. You must configure the Services in your Windows to ensure QuickBooksDBXX service restarts automatically even if it stops running due to any factors. Use these steps-

  2. Type ‘services.msc’ as a command and press Enter to launch the Services

  4. Click the Startup type and select Automatic.
  5. Set the Service Status to Running or Started.
  6. Approach the Recovery tab and go to the First Failure drop-down.
  7. Choose Restart the service and select the same for Second Failure and Subsequent Failures.

  6. If DBSM opens, scan the QB Desktop file to recreate the QBDataServiceUserXX account.
