If the dongle remains unrecognized after testing on multiple computers (to rule out a faulty USB port), the solution moves to . Optitex 15 licenses are tied to the HASP’s unique ID. The user must contact their authorized Optitex distributor with the dongle’s serial number (usually printed on the casing) and a description of the failure. Legitimate licenses are typically covered by a hardware replacement warranty under an active Support and Maintenance (S&M) agreement. The distributor will deactivate the lost ID and issue a new HASP or, in modern cases, convert the license to a software-based Softkey (virtual HASP), which eliminates the physical plug entirely.
