Does LM-X offer protection against reverse engineering and tampering with executable content?

LM-X License Manager does not provide executable code protection against reverse engineering and accidental or deliberate tampering with the executable content. If you want to use software that provides protection from reverse engineering, you will need to use a third party solution.

Please note that LM-X License Manager allows you to perform a clock check on the client side to ensure users have not backdated or tampered with their system clock.

For more information about protection against time tampering, see System clock check.

How can I obtain LM-X License Manager dongle drivers?

On top of Sentinel HASP HL Pro dongles available at X-Formation for some time, now you can also buy 2 GB Flash driverless Sentinel HASP Max dongles.

For more information about downloading the latest Sentinel HASP drivers, go to End User Tools Downloads. You can also visit our blog to learn more about driverless Flash Sentinel HASP Max dongles.

for instructions on how to get started with LM-X.

Why do I get the error "LMX_BAD_SECURITY_CONFIG"?

If you see the error "LMX_BAD_SECURITY_CONFIG" during checkout, you may have multiple security configuration files (security_config.lmx). The license may be using one security configuration file, while the application is using a different security configuration file. Both the license and application must use the same security configuration file.

To resolve the problem:

  1. Check for multiple configuration files and review the contents to determine which should be used.
  2. Ensure that the security configuration file you want to use is placed in LM-X SDK path/config/security_config.lmx.
  3. Clean the LM-X SDK of objects from the previous compilation: For Linux, run "make clean." For Windows, run "nmake clean" or use the Clean Solution option in Visual Studio.
  4. Remove the unneeded security configuration file.
  5. If you have two versions of the SDK installed on different machines (for example, one for 32-bit Windows and another for 64-bit Windows), copy the security configuration file from one machine to the other.
  6. Recompile the SDK.

How do I download the latest software?

To download the latest version of LM-X, to the LM-X License Manager download page.

See LM-X License Manager Quick Start for more details.

Do our users have to upgrade their license servers after we upgrade to a new LM-X License Manager release?

When software vendors upgrade to a new LM-X License Manager release, their end users must also upgrade their LM-X license server. If they don't do this, the new server will not work with existing licenses.

See Version compatibility
for more compatibility-specific information.

How can I lock my software to a host when using a cloud service provider?

With Amazon EC2, you can use the Instance ID for the HostID (see HostID values). However, for other cloud service providers, such as Microsoft Azure, virtual machines do not have HostIDs.

See Licensing for virtual machines and cloud computing
for further information on licensing software for cloud applications.

Compiling LM-X using Visual Studio Express Edition

You may see the following error message when attempting to compile the LM-X distribution using Visual Studio Express Edition:

'devenv' is not recognized as an internal or external command, operable program or batch file.

This error is due to different file names in Visual Studio versus Visual Studio Express. The file devenv.exe is the name of the IDE executable for Visual Studio editions. For Visual Studio Express editions, each IDE executable has a different name, specifically: Visual C++ 2005/2008/2010 Express Edition - vcexpress.exe.

To solve this problem, copy the attached batch file (scroll down for attachment), devenv.bat, to a location such as C:\Windows where it will be added to the system path and recognized from the command line. LM-X will then compile normally.
