Dear Laur,
Thanks for raising the concern.
The three USB controllers mentioned are device drivers for HASP HL key. These are loaded each time the key is connected to the machine. However, please help us by confirming the status of this problem as of now over below points.
1 - Are you able to access ACC (at http://localhost:1947/_int_/index.html ) post-installation of RTE 7.6 ?
2 - Is system crash still being observed after installation ? If yes, please confirm at when does it happen ?
3 - If any anti-virus is installed then please share its details.
Looking forward to your reply.
Regards,
Parth Kaushik
