Network license manager does not pull license from server

[krabat]

Hi all,

I have a strange problem: we use the volume license manager server, where I set up the network licenses for the users. A few days ago, a user called me and said "yeah, look. I installed LabVIEW, here, my license manager tells me that I have a (network) license, but LabVIEW keeps telling me that it's in trial mode.". Today, a user called me, telling me the same story for Flexlogger. DIAdem is also affected.

I have no clue whatsoever. Is there anyone around with the same problem?

Cheers,

Manuel

Hi krabat,

you're definitely not alone having these types of issues, there is quite an extensive knowledge base troubleshooting exactly the same problem:

Software Is Unlicensed or in Evaluation Mode Activating from NI VLM Server

But in a nutshell:

Check the permissions you set up for the user. Check if other users around him may have the same problem.

Check if he's using the SW versions he's allowed to use LV 2020 may work - SP1 may not if the license file doesn't have it.

Check if your VLM and his License Manager are compatible by versions. 
Check his firewall settings.

Last but not least - did he try to turn it off and back on? 🙂

Hei Patrik,

thanks for your suggestions.

WRT permissions: that's not for me to set. Our IT has strict rules regarding users, so those are fine. Other users around him don't have those problems, no.

SW versions: yes, those are all the allowed ones.

Firewall settings: all the same for the computers we're working on - again: set by IT, not my concern.

No, turning it off and on again did - unfortunately - not help. ^^

VLM might be the solution, but I can't tell what - presumably - exactly fixes it. I haven't heard back from the users, I'm afraid.

I'll let you know, as soon as I heard back.

Thanks!

Cheers,

Manuel

Hello @ll,

the VLM version update did fix the issue.

So: in case of doubt, install the latest version of your VLM and have fun!

Cheers,

Manuel

I ran into the exact same issue but there was a different cause and solution. I learned that I was seeing this issue of having a network license but receiving an expired evaluation message because I already had LabVIEW running on a different computer on the network. It appears that you can only have one LabVIEW application instance at a time running on networked computers if you have a named-user network license. Once I closed the other application instance of LabVIEW, I was able to start LabVIEW on the other networked computer without any trouble. The license error message was misleading because it didn't tell the true cause of the problem. I have also seen another incorrect error message about the volume license server not being available when doing the same thing on a different set of networked computers (trying to run two different LabVIEW application instances at the same time on different computers). In that case, I presume the different license error message appeared because LabVIEW had never been launched at any time using an evaluation license and therefore did not have an expired evaluation license.
