Quartus Prime license rehosted, unable to run

Hi,

We are unable to use our Quartus Prime license after switching to a new physical laptop.

Product: FPGA Dev Tools Quartus® Prime Software SW-ONE-QUARTUS

The license was rehosted from the old computer ID to the new primary computer ID. The rehost/update appears to have completed successfully, but the license still cannot be activated/used on the new machine.

Environment/details:

• Windows 11
• FlexNet Licensing v11.19.6.0
• Single-server setup
• License file path: C:\flexlm\license.dat
• lmgrd TCP port: 1800

Relevant log excerpt:

(lmgrd) Starting vendor daemons ...
(lmgrd) Started alterad
(lmgrd) INTERNAL error: Please report the following to your vendor
(lmgrd) Attempt to start a vendor daemon named "lmgrd"
(lmgrd) Started mgcld
(lmgrd) Started lmutil
(lmgrd) lmutil exited with status 0 signal = 788
(lmgrd) Since this is an unknown status, license server manager
(lmgrd) will attempt to re-start the vendor daemon.
(lmgrd) REStarted lmutil
(lmgrd) alterad using TCP-port 49985
(lmgrd) mgcld using TCP-port 49990
(lmgrd) lmutil exited with status 0 signal = 832
(lmgrd) Since this is an unknown status, license server manager
(lmgrd) will attempt to re-start the vendor daemon.
(lmgrd) REStarted lmutil

It looks like lmgrd is trying to start lmutil as a vendor daemon, and also reports:

Attempt to start a vendor daemon named "lmgrd"

Could this indicate an incorrect or malformed license.dat file, for example an invalid VENDOR/DAEMON line or wrong path to the vendor daemon? What should we check or change to make the Quartus license work after rehosting?
