Sentinel HL Key is not found in Device Manager post-windows upgrade

Hi, we use FlexLM for license serving from a server but also via the HASP driver using USB keys. I've noticed on two occasions (and more coming I fear) that the upgrade from HASP 6.65 to HASP 7.103 is failing to install the Sentinel HL Key (it's literally not there). Yet, on other occasions (including my own test systems) it's perfectly fine. 

You can see the notes here on how to install and troubleshooting which I believe are the correct instructions. 

However, if the customer upgrades (and we've had 2 possibly 3 now) they find that in Device Manager the Sentinel HL Key simply doesn't appear (even if I turn on visibility of hidden devices). This means that LMTools can see the HostID of the key (they are FLEX=9 versions with HW 3.25) but our software does not. But, like I said, only in specific instances not all the time.

Any suggestions as to what to check next please ?


Thx, Mike
