Given the following circumstances at a customer site:

1. One machine has Run-time Environment version 7.51.

2. A second machine has a version of Run-time Environment that is earlier than 7.51.

3. The customer performs rehost of a license repeatedly between the two machines.

4. An update is applied to the license on either of these machines.

A rehost operation sometimes fails with the message HASP_REHOST_ALREADY_APPLIED.

Workaround: Obtain a new SL license from the software vendor for the protected application on the target machine. Before attempting any additional rehost procedure, install the latest Run-time Environment on both machines.

LDK-8480

With some new USB chipsets, it is possible that the API hasp_update() call, used to update the firmware of Sentinel HL keys to version 3.25, will generate the HASP_BROKEN_SESSION return code, even if the firmware is correctly updated. (This issue does not occur with Sentinel HL Driverless keys with firmware version 4.x.)

Workaround: Install the latest Run-time Environment. The automatic firmware update feature of the License Manager will automatically update the firmware of the key the first time that the key is connected, without the need to call hasp_update().

LDK-2471

Sentinel Licensing API: On a computer with the Nvidia chip set GeForce 7025/nForce 630a, and where the CPU is AMD Athlon 64 X2, the hasp_read and hasp_encrypt functions may fail with error 39, HASP_BROKEN_SESSION. This problem only exists with HASP HL keys with Firmware version 3.25.

Workaround 1: On the computer described above, when error 39 is returned, call the hasp_read or hasp_encrypt function again. It is not necessary to call hasp_login again.

Workaround 2: Use Sentinel HL keys with Firmware version 4.2x.
