Vision Builder Takes Long Time to Launch Due to Error: The Description for Event Id 100 from Source Nizeroconfservice Cannot Be Found.

Issue Details

When I open Vision Builder for Automated Inspection (VBAI), it takes 3 to 4 minutes for the welcome page to show up. I Checked event system log and see the following error: 

The description for Event ID 100 from source niZeroconfService cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer. 
If the event originated on another computer, the display information had to be saved with the event. 
The following information was included with the event: 
864: ERROR: read_msg errno 0 (The operation completed successfully.) 
The specified resource type cannot be found in the image file 

Solution

VBAI can hang during launch for a a couple of different reasons:

NI Services required by VBAI are not running. 

1. Go to Start»Control Panel»Administrative Tools»Services.
2. Check that the following services are running: 
   • NI Network Discovery
   • NI mDNS Responder Service
3. If these services are stopped, right-click on the service and click Start.
4. If these services are running, right-click on the service and click Stop and then restart the services.
5. Launch VBAI again to see if the hang is resolved.

A corrupt VBAI installation is causing the hang.

1. Follow the instructions in Uninstall or Repair National Instruments Software to repair your installation of Vision Builder for Automated Inspection.

Note: To repair the installation, you will need the VBAI installation media. You can use the original USB or DVD installer you received when you purchased the software or you can download the installer from www.ni.com/downloads.

Additional Information
