For Floating and Node-locked Product Licenses -- Questions on Intel® License Manager for FLEX lm*


Where do I find a license for my software product?
If you purchased the software product, a license is included with the product, but you need to register your product to get technical support and access to product updates. If you are using an evaluation version of the software product, the license will be copied to your system during installation.  For your convenience, the license file will also be attached to an email that Intel sends you after you register.

For all floating and node-locked licenses you must obtain a copy of the license file from your license server administr ator before installing the product.

Renewal licenses must be obtained from the  Intel® Registration Center and installed manually on the system.

If you have a problem with your license or registration, submit an issue to Intel StartUp Support.


What kinds of product licenses are available?
Intel's software products use the MacroVision’s FLEX lm* electronic licensing technology. The standard license that comes with the CD-ROM or through electronic distribution is an "uncounted" license (i.e., single user license) and is not a server-based license. This means that a FLEX lm license manager is not needed to use the software product, and the software product may be used on any host.

We also offer "counted" licenses, which require an Intel® License Manager for FLEX lm running on a designated server in order to use the software product. A node-locked license enables the software product to be used only on a single distinguished client, and a floating license enables the software product to be used on any client. In either case, the client must be able to communicate with the license manager (running on the same host) to check out an available license in order to use the software product. For a node-locked license, the license manager must be running on the same host system as the software product. For a floating license, the license manager can be running on the same host or on a different host.

Both node-locked and floating licenses are sold via resellers. A list of resellers can be found by clicking here. Please indicate the type of license you are requesting.

Non-commercial product licenses are available by clicking here .
Academic, student and classroom product licenses can be obtained from resellers.
Evaluation licenses can be obtained from the Intel® Evaluation Software Center .


Is there a naming convention for the product license files?

License files must end with .lic.

For what operating systems are license managers available?
Intel's software products use the MacroVision’s FLEX lm electronic licensing technology. Floating and node-locked licenses require an Intel License Manager for FLEX lm running on a designated server to use the software product. Further information is available on the  Intel® FLEXlm* License Servers catalog. Intel® License Manager for FLEX lmis available for the following operating systems:
  • Microsoft* Windows* (IA-32 and Intel® Itanium®-based systems)
  • Linux* (IA-32, Intel® 64, and Intel Itanium-based systems)
  • Mac OS* X, version 10.4.4 and higher on Intel architecture

Each software product provides a version of the Intel License Manager for FLEX lm for its native operating system. All other versions of the Intel License Manager for FLEX lm are available by special arrangement. If you need one of these, contact Intel StartUp Support.


Where can I get the Intel License Manager for FLEX lm*?
The Intel® License Manager for FLEX lm is available from the Intel® FLEXlm* License Servers catalog.

The Intel® License Manager for FlexLM is available for download at the Intel Registration Center for customers who hold an active "counted" license. After logging in to the Intel Registration Center, select Product Downloads, select “Intel® License Manager for FLEXlm* product" from the Product list, then select the serve driver for your operating system. If you do not have access to this product at the Intel Registration Center, you may register for access.


Does the Intel® License Manager for FLEX lm work with all versions of Intel’s software products?

Starting with version 7.1 of the Intel compilers (both C++ and Fortran), and recent versions of Intel's other software products, the same Intel License Manager for FLEX lm may be used for all versions of Intel’s software product, pending operating system compatibility. Version 7.0 of the compiler and prior versions use a different license management solution as do older versions of other Intel software products. Please submit an issue at Intel StartUp Support if there is a question.


Can another license manager be used to serve Intel software products?
No. Only the Intel® License Manager fo r FLEX lm may be used to serve Intel software products. The license server shipped with SGI ProPack* for example does not work with the Intel Software Products.


Can other license managers run on the same system with the Intel License Manager for FLEX lm?
Yes. We are not aware of any incompatibilities with other license managers, so multiple license managers may run concurrently. The Intel License Manager for FLEX lm should be installed in its own directory structure, so as not to overwrite any existing license manager information.


How do I transfer a floating or node-locked license to another system?
Customer are permitted to make up to three changes to their license at the Intel Registration Center. The hostname component of the SERVER part of the license key may be changed without breaking the encryption, but the HOSTID may not be changed. Please go to this related article for the procedure to change the Host information: http://software.intel.com/en-us/articles/change--serverhost-data-node-locked-or-floating-license/


Can client systems access a license server from a different subnet?
Yes. They can be anywhere, if they can reach each other on some specific TCP/IP ports (i.e. no firewall blocks these ports), which is defined in the license file. Usually the port is 28518. For redundant server configuration, all license servers and clients can also be in different subnets. If redundant license servers are in different subnets, either the hostnames including the full domain names or the IP addresses (not recommended since they may change after a server reboot or network modification) must be specified in the license file (.lic). This can be done with any text editor since hostname information is not encrypted in the license file.


How many license servers in a redundant configuration must be running?
At least two of the three servers in a redundant configuration must be available for license serving for clients to be able to check out product licenses.


What if I need the floating or node-locked product license to run on a HOSTID that is associated with a secondary Ethernet card? How do I configure for a non-primary Ethernet card?
You must submit an issue to Intel StartUp Support. Be sure to specify the serial number for your software product. The only way we can create such a license is to use a static tcp/ip address. Please include the static tcp/ip address for the intended Ethernet card when you submit the request

Two Common Issues Using Intel® License Manager for FLEX lm on Windows/NT

  • Handling Windows* Firewall Issues with the Intel License Manager for FLEX lmProblem: The firewall for Windows XP* with Service Pack 2 prevents the client application from connecting to the FLEX lmserver on Windows XP.

    Solutions: The following solution as described applies only to Windows NT servers. If you are not running on a Windows NT server (i.e., Linux, AIX, Solaris, etc.), please use the name of the server from the installation package that is appropriate for your server’s operating system. “Imgrd.intel” is a common non-NT server name.

    On Windows NT, Windows XP with Service Pack 2 comes with a firewall which is turned on by default. If the firewall is turned on, your FLEX lm* license server daemon ( Imgrd.intel.exe) and Intel License Manager for FLEX lm license server vendor daemon ( INTEL.exe) will stop functioning. You can find more information about the firewall in Service Pack 2 at http://msdn.microsoft.com/en-us/default.aspx. †**Intel is not responsible for content of sites outside our intranet.

  • Workarounds:

  • There are two methods to make Imgrd.intel.exe and INTEL.exe function properly.

    Method A:

    Add a program exception to allow Imgrd.intel.exe and INTEL.exe to use required ports. You must execute both step 4 and step 5. Failure to do so causes the FLEX lm license server not to work.

    Note: The name of the Linux Intel server is lmgrd.intel, not lmgrd.intel.exe. So if you are using a Linux server, then the name to add in Method A, step 4 would be "lmgrd.intel" and the name to add in Method B, step 5 would be the same.

  • Click Start » Run, type Wscui.cpl, and then click OK.
  • In the Windows Security Center window, click Windows Firewall.
  • On the Exceptions tab, click Add Program.
  • In the list of programs, look for lmgrd.intel.exe. If lmgrd.intel.exe is in the list of programs, select it and click Ok. If lmgrd.intel.exe is not in the list of programs, click Browse to locate it in C:\Program Files\Common Files\Intel\FLEX lm. Select lmgrd.intel.exe, click Open, and then click OK.
  • In the list of programs, look for INTEL.exe. If INTEL.exe is in the list of programs, select it and click OK. If INTEL.exe is not in the list of programs, click Browse to locate it in C:\Program Files\Common Files\Intel\FLEX lm. Select INTEL.exe, click Open, and then click OK.

    Method B:

    Add a port exception to allow Imgrd.intel.exe, INTEL.exe and any application using these daemons to communicate as usual. You must execute both step 4 and step 5. Failure to do so causes the FLEX lm license server to error.

  • Click Start » Run, type Wscui.cpl, and then click OK.
  • In the Windows Security Center window, click Windows Firewall.
  • Click on the Exceptions tab.
  • Click on Add Port. In the Dialog Box, enter lmgrd.intel.exe in the Name field. Enter the TCP port number of lmgrd.intel.exe in the Port number field. You can obtain the port number by looking at IFLEXLmLog.txt created under C:\Program Files\Common Files\Intel\FLEXlm. In IFLEXLmLog.txt there should be a line like: lmgrd.intel.exe using tcp-port X, where X is the port number. Click OK.
  • Click on Add Port. In the Dialog Box, enter INTEL.exe in the Name field. Enter the TCP port number of INTEL.exe i n the Port number field. You can obtain the port number by looking at IFLEXLmLog.txt created under C:\Program Files\Common Files\Intel\FLEXlm. In IFLEXLmLog.txt there should be a line like: INTEL.exe using tcp-port Y, where Y is the port number. Click OK.
  • Using a Terminal Server with the Intel License Manager for FLEX lm

    Problem: You cannot use client applications running on Windows from a remote desktop connection or terminal sever client to checkout a product license.

    Solution: Using new client applications on Windows with an old product license may prevent the license checkout mechanism from working. You may therefore see the following error message:

    Terminal Server remote client not allowed.

    If you see this message, please contact the Intel StartUp Support to obtain a new product license file that allows you to use Windows-based products from a remote desktop connection or terminal server. Please note that this message applies to new Windows-based software products only and applies to uncounted product licenses (also known as Single User licenses).
