Use CodeMeter Control Center to repair an SD or microSD card-style hardkey license, after the card has been reformatted and the license has become unusable.

Prerequisites:

  • A Windows computer with an SD-compatible memory card reader;

  • The full CodeMeter Runtime software installed on that computer; and

  • An SD or microSD card-style hardkey that contains your Studio/SCADA or Embedded HMI license. (If it is a microSD card, you might also need an adapter that allows you to insert it into the memory card reader.)

Wibu-Systems provides the CodeMeter licensing solution that we use to manage hardkey licenses for Studio/SCADA and Embedded HMI. Two of the form factors that CodeMeter offers are SD and microSD (also known as µSD) memory cards, which are often better suited than USB flash drives for use in mobile and embedded devices.

The license takes up a very small portion of the card's total storage space, so you may want to reformat the card in order to use the remaining space for other things. When you do so, however, the reformatting can make the card unrecognizable as a CodeMeter device and therefore make the hardkey license unusable. If that happens, use CodeMeter Control Center to repair the card.

You must download and install the full CodeMeter Runtime software in order to perform this task, because CodeMeter Control Center is not included in the limited version of CodeMeter Runtime that is installed with the full AVEVA Edge software. You can download the software from the Wibu-Systems website at: www.wibu.com/downloads-user-software.html

You do not need to install the full CodeMeter Runtime software on the same computer where you previously installed AVEVA Edge; you may use another computer to perform this task, so that it does not interfere with your project development and/or run time. If you do install on the same computer, however, the full CodeMeter Runtime software will replace the limited version of CodeMeter Runtime that was installed with AVEVA Edge. Therefore, after you install but before you perform this task, you should confirm that AVEVA Edge can still access whatever license it was using.

To repair an SD or microSD card-style hardkey license after the card has been reformatted:

  1. Insert your hardkey into the computer's memory card reader.

  2. Open the CodeMeter Control Center, and then in the program, check the License list.

    If your hardkey appears in the list — that is, if you see either CmCard/SD or CmCard/µSD, according to the type of card — it is already recognized as a CodeMeter device. You do not need to do anything more, and you may skip the rest of this procedure. Otherwise, continue with the following steps.

  3. On the Process menu, select Repair Hardware Configuration.

    The Repair Hardware Configuration dialog box is displayed.

  4. Select Scan Hardware.

    The computer is scanned for all compatible volumes and devices. This scan might take several minutes.

  5. When the scan is finished, select your hardkey from the list of devices, and then select Repair.

    If the card is successfully repaired, a success message is displayed.

  6. Select OK to close the success message.

  7. On the View menu, select Refresh.

    The License list is refreshed.

  8. Check the License list again in order to confirm that your hardkey is recognized as a CodeMeter device.

When you are done, remember to eject the memory card in Windows before you physically remove it from the card reader.
