How can I authorize the RWIND Simulation program online with a software key on a single‑user computer?


The RWIND Simulation program is protected against unauthorized use. The program can be authorized with the online activation (a computer is connected to the Internet). Proceed as follows:

  1. Run RWIND Simulation "As Administrator." To do this, right-click the RWIND Simulation icon and select "Run As Administrator."

  2. Confirm the authorization check with the "Activate Now" function.

    This opens the "RWIND Simulation 1.xx Demo Authorization Status" dialog box.

  3. In the "RWIND Simulation 1.xx Demo Authorization Status" dialog box, select the "Software key" option in the Authorization Method section and click the "Activate Online" function in the lower part.

    This opens the "Online Activation" dialog box.

  4. In the "Online Activation" dialog box, enter your license information (a license number, an activation key, and a level of RWIND Simulation) based on your contract documents.

    Furthermore, enter an expiration date of the activation to be carried out in the middle field and a user-defined description of the work center to be activated in the bottom field.

    Then, click the "Activate Now" function to run the activation process.

    After the successful authorization, you will receive a confirmation message and it is possible to use the program without any restrictions.
This online activation uses your purchased license for the defined activation period in our system. During this time, it is not possible to activate the RWIND Simulation program with the activation key on any other computer. The assignment of the license in our system ends with a proper deactivation or after the defined activation period has expired.

Then, the activation process can be carried out again on the same or a different computer with the existing activation key.

To avoid unnecessary license assignments in our system due to unexpected computer problems on your part (defect, loss, hardware replacement, employee change, and so on), we recommend you to keep the activation period as short as possible.
