Hello,

I get a lot of license messages like the following ones. Is that a problem, or is that normal? It seems like most users do not experience problems, but some still claim, that they do not get a license. The only stuff I actually can see that is strange are the following messages in debug.log.

I use a freshly installed License Manager 2021b on Windows Server 2016

18:43:41 (MLM) UNSUPPORTED: "MATLAB" (CF738[long number]) user@computer  (No such feature exists. (-5,346))
18:43:41 (MLM) OUT: "MATLAB" user@computer  

Can anybody tell me whther this is a problem? Or what I could check?

Thanks

Matthias

Over at https://forums.developer.nvidia.com/t/no-such-feature-exists-after-updating-our-licens/135772 I find an indication that -5,346 might be related to having a LM_LICENSE_FILE environment variable that is pointing to a bad license file.

However over at https://answers.flexsim.com/questions/36397/we-follow-the-steps-for-install-the-new-license-fi.html I see something about files possibly not being "fully trusted". I do not recall ever having seen that sort of language with respect to flexlm / flexera licenses.
