Flex LM crashing on Windows 10

Flex LM crashing on Windows 10

I am having an issue on multiple Windows 10 machines where the Flex LM service is crashing multiple times a day. This seems to be linked to licenses that have been installed in the last 90 days.  The license server is being installed as part of a Creo 4 M080 install with a local license for each machine.

Did you try re-installing license manager? Update on Windows can lead to such issues.

Hi,

when you install FLEXnet from Creo 4.0 media >>> lmadmin_ptc service is created by default.

My suggestions follow:

  • stop lmadmin_ptc service
  • disable lmadmin_ptc service
  • manually define alternative service named FLEXlm server for PTC
  • use procedure mentioned on following page in FlexNet Installation using the LMTOOLS Utility section

Has PTC fixed the license server that is installed with Creo 5 or Creo 6 so that it works correctly and is not uninstalled by Windows 10 every 6 months?

Hi,

as far as I understand the situation PTC cannot solve the problem. Solving the problem is the task of Microsoft and Flexera. The question is whether any of these companies solves the problem. I guess that problem resolution has very low priority, because of existence of 2 workarounds.

W1: Deinstalllation/installation of FLEXnet, i.e. lmadmin_ptc service.

W2: Disabling lmadmin_ptc service + manual creation of Flexmlm server for PTC service.

Re: Flex LM crashing on Windows 10

If that were the case I could go out and get the latest version of the Flexera software but it will not work with a PTC product. PTC licenses and modifies the Flexera product and then modifies it to disable features like revoking licenses. This is just an issue with the PTC modified version. The version included with Creo 4 is still 11.14.2 from 2016. The version that is included with the latest version of Creo 6 is 11.14.2 from 2016. This is very much a PTC issue.
