License Information

TASKING products are protected with TASKING license management software.

License key

You need a license key when you install a TASKING product on a computer. When you order a TASKING product from TASKING or one of its distributors, a license key will be sent to you by email or on paper.

See the TASKING License Management (TLM) Support page for information on obtaining a license.

Improved Verbose Logging

You can set the TSK_LOG_VERBOSE option in licopt.txt, or as an environment variable, to different verbose levels.

With level 3 or higher, detailed license configuration information is shown, which is useful for debugging licensing problems. For example, it shows the environment variables or options used, the license key and the search path.

Support for wait for a free license

You can now set the TSK_LICENSE_WAIT option in licopt.txt to a configurable time period to wait for a free license seat to become available instead of directly terminating when a license request is denied.

Wait for Available Process

If your license specifies a maximum number of processes you are allowed to use, you can set the TSK_PROCESS_WAIT option in licopt.txt, or as an environment variable, to the parallel process time-out (default: unlimited). This specifies the number of seconds the system is allowed to wait for a process to run if the maximum number of parallel processes permitted by the license is already running.

Better Support for Comments

In all license files (licopt.txt, licdopt.txt, licfile.txt, licdfile.txt, licdaccess.txt) you can add comments, not only on a separate comment line, but also at the end of a line. Comments start with the # character.
