Visualization license and multiple workers on same machine

Did PTC change how licensing works for multiple Creo workers on same machine?  We previously had  1 PROE_FoundationVis license for multiple workers set up on our visualization machine for many years as directed both here: https://www.ptc.com/en/support/article/CS29308 and here: https://www.ptc.com/en/support/article/CS473636 but when our contract was renewed, it seems PTC removed the  DUP_GROUP = "UHD"  directive from the PROE_FoundationVis license (as well as our Creo Advanced and Creo Advanced Professional licenses), and now each worker seems to pull a license.  That directive allows “Same user on same host and same display consumes one license even with multiple xtop processes” -- Found out the hard way when our extra workers went to start up and I got 1200 emails informing me that my CAD worker failed to start.  Anyone know if this was intentional on the part of PTC?  I have a case open - and I tried reaching out to License Management but got disconnected after being on hold for 20 minutes.

A colleague directed me to this support article, https://www.ptc.com/en/support/article/CS470419?source=search which explains that:

“The current Foundation license used for publishing workflows is planned to be replaced in the future by a dedicated unattended publishing license specifically designed for publishing operations “

and

“Until the unattended publishing license becomes available, enabling the Creo Multi-Launch feature on the Foundation license may be required to maintain the same publishing behavior that was previously available”

 

So until further guidance is provided by PTC in regards to this new unattended publishing license, we generated a new license file with the Creo Multi-Launch option enabled, which resolved the issue.

I just discovered I have the same issue. Same user on same host and same display is now consuming one license each session instead of just one license.

Check out this article:

https://www.ptc.com/en/support/article/CS468670

I checked and ours was already set to Creo Multi Launch. I downloaded the license file again and this fixed the issue.

    Thanks for this -- there is another article about Multi-Launch at https://www.ptc.com/en/support/article/CS469504

    Of particular concern is the fact that they say that this can not be used for workers.  That will require an “Unattended Creo License” -- “ Is not a substitute for server‑based or worker‑based licensing “ as well as stating “In the future, Server‑side or automated workflows will require a Creo Unattended (Server) license. Details will be shared accordingly.”
