Why does a message appear in STEP 7 stating that there is not a license key present even though the relevant license key is installed?

Below you will find information on the causes and the remedies to remedy the behavior described above.

1. Incompatible time zone set on the computer

Please check whether you have one of the following time zones set on your computer:

  • (GMT -03:30) Newfoundland
  • (GMT +03:30) Teheran
  • (GMT +04:30) Kabul
  • (GMT +05:30) Bombay, Calcutta, Madras, New Delhi
  • (GMT +09:30) Adelaide
  • (GMT +09:30) Darwin

STEP 7 cannot find any license key in these time zones with a "half" hour.

Set a different time zone. For example, instead of "(GMT +09:30) Darwin" select the time zone "(GMT +10:00) Brisbane". The Unlock Copy License (UCL) is recognized as usual in time zones with a "half" hour.

This behavior has been corrected as of Automation License Manager V3.0.

2. Licenses not displayed in the ALM

You have previously used a version of STEP 7 from V5.3 onwards on your computer, and your license key has been approved as error-free up to now. A message now appears indicating that the license key for STEP 7 cannot be found. Furthermore, the licenses are no longer displayed in the ALM. However, if you log in under another user name, the license key is found properly.

STEP 7 creates a file for each license query. If there is a large number of files, the behavior described above occurs after some time.

In order to make the licenses visible again in the Automation License Manager and to be able to restart STEP 7, you must reduce the number of files in the "S-1-5-18" and "MachineKeys" folders.

  1. In Windows 10 Explorer, navigate to the "C:\ProgramData\Microsoft\Crypto\RSA" directory.
  2. Mark the "MachineKeys" folder and delete all the files older than two days.
  3. Then mark the "S-1-5-18" folder and here also delete all the files older than two days.

You can then see the licenses again in the Automation License Manager and you can restart STEP 7.

Note that this path contains other folders. If you have used this remedy we recommend that you check the access data for T-Online when you next start up your computer.

3. Upgrade license key was transferred to the hard disk

If you have transferred the upgrade license key of STEP 7 to your hard disk, then when you start your new version of STEP 7, you get the message stating that the license key is invalid. The cause for this behavior is that you now have two different license keys on your computer, but no valid license key for the new version of STEP 7.

You still have to upgrade the license key. Information about this is available in

Once you have made the upgrade, you can start your new version of STEP 7.

Refer to the information in the Online Help of the Automation License Manager: "Installing License Keys". You cannot install upgrade license keys during Setup.

4. Automation License Manager Service not started

Check whether the Automation License Manager Service is started in the administration settings of your computer. If the Automation License Manager service is terminated or interrupted, you must restart it.

  1. Simultaneously press the "<Ctrl> + <Alt> + <Del>" keys on your keyboard to open the Task Manager under MS Windows 10.
  2. Switch to the "Services" tab in the task manager.
  3. Right-click on the "almservice" service and select the "Start" or "Restart" function from the context menu. The license key is then recognized by STEP 7.

5. Incompatibility of the "Mobile Connect" software of a provider (T-Online, O2 or Vodafone)

Generally, this concerns mobile computers like laptops and field PGs that rely on a mobile Internet connection. "Mobile Connect" software of a provider like T-Online, O2 or Vodafone is installed on these computers. This software includes an optimization component for communication. This optimization component is not compatible with the Windows communications structure, which has the following effect on the Automation License Manager:

  • The Automation License Manager hangs or cannot be started.
  • SIMATIC products hang or cannot find the installed license key.

You must disable the optimization component when setting up the "Mobile Connect" software. The following remedy is based on the Vodafone Mobile Connect software.

  1. Press the "Windows key" on your keyboard and enter the search term "Add or remove programs".
  2. Mark the "Mobile Connect" software and click on the "Change" button. The Vodafone Mobile Connect Installer starts.
  3. Select the "Modify" function in Program Maintenance and then click on "Next".
  4. Disable the "Optimization Software" option as shown in Fig. 1.
  5. Click on the "Next" button to continue the installation. After installation you must restart your PC.

Fig. 1

If you are installing "Mobile Connect" software for the first time, you must select the "Custom" function after starting the Setup. In this way you get to the dialog where you can disable the "Optimization Software" option.
