If a trial/evaluation license installs fine but a purchased license does not install, it is likely that
either the mac address is wrong in the license file or the license file itself is bad. A
purchased license differs from a trial/evaluation license in that the purchased license only
works on the machine where the mac address is provided. That mac address must match the
mac address in use, and if running on a VM, the physical mac address for the machine is not
the same as the mac address of the VM (see #7 above).
Second, it is possible that the licens e file itself is bad or corrupt. The feature name in the
license file must be either IPSC_DEVICES or IPSC_DEMO. If it is HPSM_DEVICES, contact the
licensing support team and request another license. When doing so, make sure to instruct
them to generate a new license instead of re-sending the original license as they will not
know the original license is bad unless you tell them.
The license has readable text in the first half and encrypted content (SIGN=xxxx ...) in the
latter half that matches the readable content in the first half. Content of license files SHOULD
NOT be changed/edited at any time. Any edit to the readable content will no longer match
the encrypted portion and the file is now corrupt and unusable. If “SIGN=0” in the latter half
of the file, it is corrupt and a new license file needs to be generated.
8. Make sure license files are present under C:\ProgramData\HP\HP Print License
Service\LicenseFiles. By default, C:\ProgramData is a hidden folder. Either un-hide hidden
folders to view this folder or type the folder name (C:\ProgramData) directly in the address
bar.
9. Log files can provide clues as to what may be causing the problem. Two log files exist for the
licensn e service as such:
C:\ProgramData\HP\HP Print License Service Files\Flexera.log
C:\ProgramData\HP\HP Print License Service Files\HPPLS.log
The Security Manager service log can also provide valuable information:
C:\Program Files (x86)\ HP JetAdvantage Security Manager\log\HPHPSM_Service.log
For example:
