Licensing and Maintenance

Answer

Single User License: The software can be installed on as many computers as desired on the licensed site, but only the computer with the proper "USB Key" (or "dongle") plugged into an available port will be able to run the software in full mode.

Local Network License: With this license the software can be installed (or accessed) in local computers on the licensed site, without the need of the USB Key in each computer. With this licensing option, a "Net USB Key" is installed on a designated license server which can be in the local office or on a remote location. Licensing is strictly provided per designated office location. Up to 2 users can simultaneously access the software at any time (more can be added with additional fees). On Network Licenses, to control potential users the network policy establishes a limit on the range of IP addresses of local clients that can access the software. The smallest local network license for a specific site allows up to four subnets (with four unique third octets) for clients located in the licensed site(s). If the network at the local site requires more than 4 of those subnets then the site will need to purchase additional seats. Multiple offices with local network licenses can be managed from one license server and shared between users in the licensed sites.

Answer

You can continue to use the software beyond the maintenance expiration and without payment of the annual maintenance. However, free technical support will not be available and you will not be able to use maintenance releases or software upgrades that are released after the expiration date on your USB Key(s). Also, please note that compatibility with future operating systems will only be provided to the current maintenance releases. Our website allows users to download any previous releases of Ensoft software so you will always have access to the release that works with your maintenance expiration date. The pricing of maintenance renewals have small increases with time after expiration.

Answer

Our policy allows for a one-time, free permanent transfer of each software license.

Software

Answer

Software manuals are installed with each program. The easiest way to access the manuals is from the "Help" menu. The manuals can alo be accessed from the Windows "Start Menu" (usually in lower left corner of the Windows Desktop screen). For instance, for LPILE, you can access the User's and Technical Manuals at:

Start Menu > All Programs > Ensoft > Lpile2016 > LP2016 Technical Manual

Start Menu > All Programs > Ensoft > Lpile2016 > LP2016 Users Manual

The Technical Manual is copyrighted and only works when you have the proper USB Key connected to the computer in use. The User's Manual is a standard Adobe PDF file. In order to open either manual you will need Adobe Acrobat or Reader (free from adobe.com) v8 or newer.

Answer

If the Technical Manual is not opening with Acrobat or Reader (while having the LPILE USB key connected to the computer in use) then perhaps the Adobe software is not configured correctly. Start Adobe Reader (or full Adobe Acrobat) then click on "Edit/Preferences" and "Internet" under "Categories". Please make sure that a check mark is placed under "Display PDF in Browser" then click OK and exit Reader. You can then try to run the Technical Manual once again.

Answer

By default the example files are installed on a folder in the root drive. For instance, for LPILE, you can see the example files in the following folder:


                  (root drive) \ Ensoft \ Lpile2016-Examples
                  
A chapter in the User's Manual for each program includes some additional information regarding each example problem.
Answer

Users can download, install and run -free of additional charges- any release of our products that was made prior to the maintenance expiration date. Software releases can be accessed from the Downloads page.

Answer

    The most common causes are as follows:
  1. The correct USB Key is not plugged into the user’s machine. Plug the appropriate USB Key for the desired program into a functioning USB port on the user’s machine.
  2. The USB Key is not plugged in correctly. When recognized by the user’s machine, there will be a small solid green LED light near the tip of the USB Key. If this light is not present or blinking, the USB port may not be functional. Please try plugging the USB Key into other available USB ports on the machine or even another computer where the desired program is installed. If this does not solve the issue, then please go ahead and contact Ensoft Technical Support .
  3. The USB key is plugged in and being recognized (green LED constantly visible) but the program still runs in Demo Mode, why? If this is the case, the maintenance on the user’s license may have expired, and the user is trying to run a version of the program released after the maintenance expiration. The user can check this from “Help” menu and Selecting “About”. This will give information about the software version, as well as the USB Key. If the Release Date of the program is newer than the Maintenance Expiration Date, then the user will be unable to run this program version. In order to do so the Maintenance must be renewed, and can be done so by contacting our Sales Department
Answer

Upon completion of your upgrade/renewal order you will receive an email from Ensoft (either from ' or from '') with instructions and the upgrade file. To complete the upgrade you will need to run the "Ensoft Key Inquirer" utility (see further below how to run this utility). In the dialog window select the "Browse" button under "Upgrade File" section in lower right and point to the place where you saved the file attachment that Ensoft sent to your office for the maintenance upgrade (a file with the extension "filename.upd"). The "Ensoft Key Inquirer" utility is installed with the software. It can be accessed from the Windows Start Menu (usually in lower left corner of the Windows Desktop screen). For instance, for LPILE, you can access the Ensoft Key Inquirer at:


                      Start Menu > All Programs > Ensoft > Lpile2016 > Ensoft Key Inquirer
                  
or for Windows 10:

                      Windows Start Menu > All Apps > Ensoft > Lpile 2016 > Ensoft Key Inquirer
                  
The 'Ensoft Key Inquirer' utility simply calls the 'ensoft_key_inquirer.exe' application that is installed in the program's installation directory.

Answer

Engineers would consider the purchase of both (LPILE &s; GROUP) when they have designs of foundations that involve single piles (under lateral loads) as well as other designs involving pile groups with large caps. The LPILE program is dedicated to the modeling of single piles and thus have several advanced features that are not present in the more general GROUP program. Some of those unique features in LPILE are the following: critical pile penetration, buckling analyses, push-over analyses, LRFD code compatibility and some ACI318 design aides for reinforced-concrete pile section(s). The GROUP program has a broader scope than LPILE since it covers load transfers in the lateral as well as axial directions, plus a 3D frame analysis for compatibility of deformations and equilibrium while assuming a rigid pile cap. It has most features from LPILE other than those specific missing items that were mentioned earlier. However, GROUP is not able to model a single pile since it will generate a singular matrix when it tracks compatibility of deformations and load equilibrium for the framed system.

Answer
To use LPILE/ SHAFT/ PYWALL/ APILE/ TZPILE/ STABLPRO, the user needs the following minimum system configuration:
  • Any personal computer with an Intel™ Pentium™ or newer processor
  • A hard disk with at least 50 MB of free space.
  • Microsoft Windows™ 2000, XP, VISTA, Windows 7, Windows 8, Windows 8.1 or Windows 10 in either 32-bit or 64-bit releases. A release of the Microsoft Windows™ system that is newer than those listed will need a new update of the software.
  • Minimum of 640 KB of free RAM memory.
  • Open (available) USB port (v2 or newer).
  • Graphics card compatible to the Microsoft Windows™ operating system that is being used.
  • A mouse or similar pointing device.
  • (Optional) Any Windows-compatible printer.
In addition, GROUP requires the following:
