The License information page shows details of the current license status and lets you reactivate your license if any changes have been made.

In the Products section, under Features, you can see which consumers you are able to use, and which type of instructions you can run according to their prefix pattern. Available consumers and prefixes are listed below under License requirements for consumer applications.

License information page

Reactivating licenses

To reactivate a license after it has been updated by 1E, all you need to do is to click the Reactivate button on the License information page. It takes a few minutes to retrieve the new license information and the page caches its displayed information for around 10 minutes. After this time you can update the view by clicking the Refresh button, which updates the information displayed on the page and in the lower right-hand corner of the browser. This will all take place with no disruption to Tachyon.

If you do happen to encounter any issues with reactivating your license, please contact 1E Support for details on the alternative way to get your license updated successfully. Please refer to Troubleshooting: 1E Support contact details on how to contact 1E Support.

License requirements for consumer applications

For any application, tool or feature to use instructions, its consumer and prefix pattern must be registered in your license. The table below shows the consumers and prefix patterns that are typically included in a Tachyon license. The table also includes other applications where instructions - and therefore licensing - is not applicable. Tachyon expects to find the license file in: %PROGRAMDATA%\1E\Licensing on your Tachyon (Master Stack) Server.

Explorer application provides functionality to run, approve and schedule instructions, view Tachyon managed devices. Used to investigate, remediate issues and manage operations across all your endpoints in real-time.

If you want to use instructions developed by third parties, your own developers, or 1E developers on your behalf, then you must ask 1E to register the third party and customer prefixes in your license. Please refer to Developing your own instructions.

You cannot create or update instructions using other prefixes because they must be signed by others.

  • Software waste identification – shows unused or rarely used software which are probably the two largest form of software waste and enables to reclaim
  • License Demand based on different metrics for vendors

Now, you can financially quantify all software waste by identifying and controlling unused software across your enterprise and improve your compliance status.

Application MigrationApplicationMigrationN/AN/A

Application Migration intelligently automates the migration of applications during a Configuration Manager OS deployment. Using migration rules (defined by an administrator), previously installed applications can be reinstalled, upgraded or replaced with an alternative during an OS deployment task sequence.

These rules can include usage criteria, allowing you to choose to only install previously installed applications if they were being used, or perhaps replace a rarely used application with a less costly alternative. This functionality enables applications to be actively rationalized during an OS migration exercise, standardizing on products and versions and reclaiming unused software.
