Problem: The detected dongle's serial number has an unexpected value.

If the error occurs in DinkeyAdd: Check that the serial number of the dongle being programmed is in the range specified under Advanced Options on the General tab. You can quickly check the dongle serial number using DinkeyLook.

If the error occurs in your protected software: Check that the serial number of the dongle matches the range specified when protection was added. If you are using the MATCH_DONGLE_NUMBER API flag, check that the value of the DRIS dongle_number field is correct. To check an end-user's dongle serial number, ask the user to use Tools > Generate Diagnostics in DinkeyChange, and send you the diagnostics file. You can open this file using DinkeyLook to check the details of the user's dongle.
