Question 2

Do I need a license key to run ASPEN OneLiner/Power Flow?

Accepted Answer

Yes. The OneLiner/Power Flow program will run only when it finds an ASPEN license key with available seat. The key type and method of access settings are stored in the windows registry. You must specify this configuration setting using the OneLiner/Power Flow Configuration program.
 
Following key type and method of access options are available:
-    Local access to Sentinel HL-max or HL-net key: ASPEN dongle of green or red color must be connected to the local machine USB port. The picture below shows various forms of Sentinel HL-max (green) and HL-net (red) keys.

-    Network access to Sentinel HL-Net key: ASPEN dongle of red color must connected to the USB port of the network license server on LAN. The picture below shows various forms of Sentinel HL-net keys.

-    Local or network access to software SL key: SL key is a unique software code created by ASPEN from the fingerprint of the license server. You must run the ASPEN SL Key admin tool to create the host fingerprint file to send to ASPEN. You must install the SL key C2V file received from ASPEN to the host machine using the Sentinel Admin Control Center software. The host license server can be the local OneLiner/Power Flow computer (local access), or a dedicated license server on LAN (network access).

Question 3

How do I determine what “License key type and method of access” configuration to select on my machine?

Accepted Answer

Select “Local access to HL-max or HL-net key” if you have an green ASPEN USB dongle, or a red one and there is no “SS” printed on the key’s sticker label.
Select “Local or network access to HL-net key’s Sentinel Sector” if you have an red color ASPEN USB dongle and there is “SS” printed on the key’s sticker label. The key can be connected to your computer USB port or to a network license server machine on your local area network. Also use this selection if you found it is the active configuration on another OneLiner machine on your local area network.
Select “Network access to SL key” if you have received a SL key license file from ASPEN and applied to your machine. Also use this selection if you found it is the active configuration on another OneLiner machine on your local area network.

Question 4

Do I need to set up a network license server to run ASPEN OneLiner and Power Flow?

Accepted Answer

A network license server is required to share the network seat(s) in you HL-net or SL key among OneLiner/Power Flow machines on a LAN. There is no need to set up a separate license server if you plan to user the ASPEN key on a single machine exclusively.

Question 5

OneLiner startup failure with error message: "Unable to locate a Hasp HL key on the network. Program abort."

Accepted Answer

This error message indicates that: 1) OneLiner configuration for Key Type and Method of Access on this PC is set to "Network access to HASP HL-Net key". And 2) The program had failed to connect to the ASPEN Network hardware key on the license server for license authentication.
 
TO TROUBLSHOOT THIS ERROR

3.  Locate the key with vendor id 42251 and click on the Sessions button in the Actions column to view details of the current network connection sessions of the key.

Question 12

Network Access to HASP HL-Net Key discontinued

Accepted Answer

ASPEN OneLiner, Power Flow, and DistriView software (ASPEN software) released after January 1, 2022, will no longer work with the configuration “Network access to HL-Net key”.

The best way to find out the key type and the method of access you are using is to start your ASPEN software and execute the Help | About This Program command. You will see a dialog box that looks like this:

If the text left of the arrow reads “Network access to HL-Net key S/N xxxx”, then please read on. Otherwise, you can stop because the change will not affect you.

First, we suggest you write down the 4-digit hex serial number xxxx of your existing key (the key number in this example is A91C).

The “Network access to HL-Net key” configuration requires a network connection to the Hasp License Manager software. This software has not been updated for many years and it is becoming obsolete. In many cases, it adversely affects ASPEN software’s reliable and secure operation.

To continue using ASPEN software with a shared network license key you will need to replace your HL-Net key with one of the following:
A USB key (hardware key) known as “HL-Net key with a Sentinel Sector”
A software key, also known as an “SL key”.
Both of the above key configurations have been available in all the existing major versions of ASPEN software: OneLiner/Power Flow since version12, and DistriView since version 10. These license key types utilize the Sentinel® license manager, which is bundled in the same package as the key driver and requires no separate new installation. The license manager also comes with an easy-to-use Sentinel Control Panel that lets users monitor and manage the license usage. For example, you can use the Sentinel Control Panel to reset inactive network sessions to make the seats on the key available for other users. The Sentinel® license manager is actively maintained by the vendor (Thales) with regular security updates and feature enhancements.

For more information on the installation of these keys, please download the following manuals:
Hardware key: OneLiner Getting Started Manual or DistriView Getting Started Manual 
SL Key: SL-Key Administration Manual 
You need to take the following steps as soon as possible:
Contact ASPEN support <support@aspeninc.com> with a request to exchange your existing HL-Net key for a new HL-Net key with Sentinel Sector, or an SL key. Please provide ASPEN the serial number of your existing HL-Net key, and in the case of a hardware key, the shipping address for the new key. The exchange for "HL-Net key with Sentinel Sector" is free of charge for all users with an active software maintenance subscription.
Install the latest Sentinel® LDK and Sentinel HASP® Run-time Environment on the license server computer, and connect/install the new key to the computer that host the network key.
Change the ASPEN program configuration on each application PC to match the new key type.

Q. How can I tell if “HL-Net key with a sentinel sector” (hardware key) or “Sentinel Software SL key” (software key) is the right choice for me

A. You will need to take the following into account:
ASPEN programs will work the same way with both key types.
Both key types require the latest Sentinel® LDK and Sentinel HASP® Run-time Environment software on the license server.
The hardware key requires a USB port on the license server computer.
The software key is created based on a “fingerprint” of the license server computer. The SL key can stop working, be damaged, and even lost if changes are made to the server hardware or operating system when the key is active in the system. A hardware key is unaffected by these changes.
The exchange for SL software key will require an additional fee, which will be calculated based on the number of seats to be programmed in the key.

Q. How can I tell if “HL-Net key with a sentinel sector” (hardware key) or “Sentinel Software SL key” (software key) is the right choice for me

A. You will need to take the following into account:
ASPEN programs will work the same way with both key types.
Both key types require the latest Sentinel® LDK and Sentinel HASP® Run-time Environment software on the license server.
The hardware key requires a USB port on the license server computer.
The software key is created based on a “fingerprint” of the license server computer. The SL key can stop working, be damaged, and even lost if changes are made to the server hardware or operating system when the key is active in the system. A hardware key is unaffected by these changes.
The exchange for SL software key will require an additional fee, which will be calculated based on the number of seats to be programmed in the key.
