The supported versions of Tecplot Focus are listed in our Support Policy.
Do I need a license key to run Tecplot Focus?
Yes. Tecplot Focus licenses require a license key file in order to run.
Do I need to install a license manager to run Tecplot Focus?
Only Tecplot Focus network licenses require a license manager installation. Single-user Tecplot Focus licenses do not. For more information on license management for network licenses, refer to the Tecplot License Manager Support FAQ.
Do I need a new license key to upgrade from Tecplot Focus 2010 to Tecplot Focus 2011?
Yes. Your key for Tecplot Focus 2010 will not work with Tecplot Focus 2011, so you will need to request a license key.
How can I get a license key?
The primary method for requesting a license key is through our automated Software Activation page, which is open to all customers with current Software Maintenance Service (SMS). In most cases, you will receive a license key immediately after requesting it, although it may take up to one business day.
If you do not have current SMS, you will need to contact technical support to request your license key.
When requesting your license key file, please include the following information:
- Your Tecplot Focus license number. It is in the form L#####.
- Your myhostids.txt file (or its contents copied into the e-mail), which Tecplot Focus creates in its installation folder when you install Tecplot Focus. Use the myhostids.txt in this location for single-user licenses (if you have a Tecplot Focus 2008 installation, the file is created in the bin folder inside the installation folder). For a network license key, include the myhostids.txt file from the license manager installation folder. For Tecplot Focus 2008 license key requests, specify whether the license key is for a laptop or a desktop computer.
I installed the demo version of Tecplot Focus and now I want to install the purchased version. Do I need to uninstall the demo version first?
No, the installation of Tecplot Focus remains the same regardless of the license type you choose. You only need to request a license key and replace the demo license key with it. The myhostids.txt file will be required to complete the license key request. If you cannot find your myhostids.txt file in the Tecplot Focus installation folder, you can create it by doing the following:
For single-user licenses on Windows platforms, run the gethostids.bat batch file (double-click on it). This file resides in the bin folder in the Tecplot Focus installation folder. When you run the batch file, it will create a file called myhostids.txt in the same folder (for Tecplot Focus 2008) or in the main installation folder (for Tecplot Focus 2009 and Tecplot Focus 2010 and Tecplot Focus 2011).
For single-user licenses on Linux, Unix, and Mac platforms, you must reinstall Tecplot Focus and choose the single-user license type during the installation. The installation will create the myhostids.txt file and place it in the Tecplot Focus installation directory.
For network licenses, install the license manager and use the myhostids.txt file located in the license manager directory.
I tried to request a license key for Tecplot Focus 2010 or Tecplot Focus 2011 from the Tecplot Web site, but I was unable to complete my request. How can I request my license key?
It's possible that your myhostids.txt file has become corrupted. You can check it with the following steps.
Open your myhostids.txt file (in the Tecplot Focus installation folder) in a plain text editor. The file should resemble the following:
<hostid>
<disk>00000000</disk>
<ether>000000000000</ether>
<internet>000.00.000.000</internet>
<user>aaaaaa</user>
<host>aaaaaaa</host>
</hostid>
If you find that any pair of the tags (in the form and ) appear more than once in the file, you can remove the duplicate content and try your license key request again. If you find the file appears empty, make sure that Tecplot Focus supports your operating system and verify that you installed the proper installation.
How do I install my license key after I receive it?
If you request your license key through our Web site, you should receive an e-mail with your license key file, named tecplotlm.lic, attached to it. If you requested a license key for a single-user license, place the license key file in your Tecplot Focus installation folder, replacing the default tecplotlm.lic file. If you requested a network license key, place the tecplotlm.lic file in the license manager installation folder.
If you received your key file from our technical support team, you may receive an e-mail with the key file information embedded in it, instead of in an attached file. In that case, replace the contents of your tecplotlm.lic file (in your license manager installation folder for network licenses, or in your Tecplot Focus installation folder for single-user licenses) with the text shown in the e-mail between the ** start ** and ** end ** markers.
I want to install Tecplot Focus on a new computer. Do I need a new license key?
If you have a single-user license, you will need a new license key. Install Tecplot Focus on the new computer and then request a license key (including the myhostids.txt file from the new computer's installation). If you have a network license, you will not need a new license key. Install Tecplot Focus on the new computer, choose the network install mode, and include your license server name when prompted. Tecplot Focus should run successfully, as long as your license manager is set up correctly.
Can I run the 2010 and 2011 versions of Tecplot Focus on the same computer?
Yes. Both versions of the product can run on the same computer.
Can I run Tecplot Focus, Tecplot 360, and/or Tecplot RS on the same computer?
Yes; the products can run on the same computer without conflicting with each other.
Can Tecplot Focus run on a virtual machine?
You can run Tecplot Focus on a virtual machine with a network license, but the single-user license key does not allow it. If you need to use Tecplot Focus on a virtual machine with a single-user license, please contact us and explain the situation.
When installing Tecplot Focus on a Windows platform, I receive a Windows system error message that halts the installation. How do I fix this?
A Windows system error (code 1935 or 1303) can occur when installing Tecplot Focus on the Windows 7 or Windows Vista platforms. This can be resolved by right-clicking the .exe installer file and choosing "Run as Administrator" from the context menu.
When opening Tecplot Focus on a Windows platform for the first time, I receive errors citing a missing configuration and/or font file. How do I fix this?
These errors indicate that Tecplot Focus cannot find the configuration file, tecplot.cfg, and/or the font file, tecplot.fnt, in the Tecplot Focus installation folder. This is usually resolved by restarting the computer.
If that doesn't work, Go to Start > Control Panel > System > Advanced System Settings and click on the Environment Variables button. Make sure there is an environment variable named TEC_FOCUS_YEAR, where YEAR is the Tecplot Focus product year. For example, the environment variable for Tecplot Focus 2011 is TEC_FOCUS_2011. Make sure the value of this environment variable is the full path to the installation folder. If the error still occurs, check this folder for the tecplot.cfg and tecplot.fnt files. If they do not exist, locate the files in the factorydefaults subfolder and copy them to the main installation folder.
When opening Tecplot Focus on a Windows platform for the first time, I receive a "pythonutil.dll could not be loaded" error. How do I fix this?
This error indicates that Tecplot Focus cannot find the proper build of Python 2.5.x installed on the computer. This is often caused by the existence of a 32-bit version of Python on the computer prior to installing the 64-bit version of Tecplot Focus (or a 64-bit version of Python with a 32-bit version of Tecplot Focus). If you uninstall Python 2.5.x and Tecplot Focus and then reinstall Tecplot Focus, the problem should be resolved. Alternatively, you can upgrade to Tecplot Focus 2010 or newer, which embeds the Python install directly into Tecplot Focus to avoid issues with standalone installations of Python.
