Error -67033 When Starting LabVIEW Web Service

Issue Details

• When I start my LabVIEW Web Service, I see error -67033. What causes this?
• When I publish my LabVIEW Web Service on the NI Web Server, LabVIEW complains that "a Web service already exists with the input name."
• How can I resolve the error below when I publish my Web Service? I have already tried changing the name of the Web Service.

There was an error running the web service on the debug server: Error -67033 occurred at NI Web Service Debug.lvlib:Add Web Service.vi

Possible reason(s):
LabVIEW:(Hex 0xFFFEFA27) LabVIEW Web Services: A Web service already exists with the input name.

Solution

This error occurs when publishing a Web Service that already exists. Follow the steps below to resolve the error:

1. Ensure that only one Web Service with this name is published.

• Change the name of the Web Service from the LabVIEW project and try re-publishing it.
• If publishing to the Application Web Server:
  1. Navigate to http://localhost:3582/web-config/web-services in a browser.
  2. From here, unpublish any Web Services with the same name as the erroring Web Service. Select a Web Service and click Unpublish from the top, as shown below.
• If publishing on the Debug Server:
  1. Right-click the Web Service and select Application Web Server >> Stop (Debug Server).
• If publishing on the NI Web Server, move to the next step.

2. Manually force the Web Service to stop.

• From the Windows start menu, search for "Command Prompt". Right-click the application and select Run as administrator.
• Set the current directory to  C:\Program Files (x86)\National Instruments\Shared\LabVIEW Run-Time\20XX\LVWS where 20XX represents the version of LabVIEW Run-Time being used. The full command is:

cd "C:\Program Files (x86)\National Instruments\Shared\LabVIEW Run-Time\2020\LVWS"
 

• Enter the command below to stop the Web Service. Note: <Web Service Name> represents the name of your Web Service.

NIWebServicePublisher.exe "<Web Service name>" /Embedded /uninstall


3. If the Web Service has been built into a LabVIEW executable, ensure that Windows has granted permissions to NIWebServicePublisher.exe.

• When the executable is launched, a Windows pop-up should appear asking to grant permissions to NIWebServicePublisher.exe. If this does not appear, follow the steps below:
  1. Navigate to C:\Program Files (x86)\National Instruments\Shared\LabVIEW Run-Time\20XX\LVWS  on the host PC, where 20XX represents the version of LabVIEW Run-Time being used.
  2. Right-click NIWebServicePublisher.exe and select Run as administrator.
  3. When the pop-up appears, select Show more details and then Change when these notifications appear. Configure the notifications to always appear.
  4. If the pop-up still does not appear, open User Account Control Settings in Windows. Change the option to Always notify.
  5. Re-launch the executable, and verify that the Windows pop-up appears. Grant permission to NIWebServicePublisher.exe.
