An error occured-The NI System Web Server is not running

Go to solution

I am still encountering this problem.  I had a trial version of NI software from 2011.  It had expired, so I decided to download a new trial version for Labview 2013.  For this purpose,  I uninstalled the old version and re-installed the new version.  I extended its trial period from 7 days to 45 days.  After doing this step, I ran into the error that is listed on the message board.   One of the message boards suggested to repair NI software.  I did this and re-booted the computer according to the instruction in the pop-up message..  However, the same error remains.   Now, I found this thread that suggests to repair the NI software a second time.   I have started this process, but it takes a long time. 

Any ideas on overcoming this situation?

Do I need to change some registry setting or file to get the software to point to the right web server?

Hi kijijisale,


Since you have tried all the previous troubleshooting steps, let’s see if the service can be manually started.

Navigate to Start >> Control Panel >> Administrative Tools >> Services >> NI System Web Server. Left click the NI System Web Server and in the top of the dialog box click Start. Are you able to manually start the service?

The server does start.  After that, when I tried to launch the examples, I got a different error indicating that Ni Help Server could not be found.  Any other ideas?

Did you receive the error before extending the LabVIEW 2013 trial from 7 to 45 days?

Also, did you ever receive the error with LabVIEW 2011?
