How to renew an activated RWIND Simulation program license based on a software key online before the activation period expires?


The RWIND Simulation program is protected against unauthorized use. If the software key is authorized, the program is only authorized for a specific activation period, which must be defined by the user. After this period, the program automatically switches to demo mode; the previously used license is again freely available for a new activation. To avoid reactivation on the same standalone computer, it is possible to renew the license online (computer is connected to the Internet) by specifying a new activation period before the activation period expires. To do this, proceed as follows:

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

  2. Select the 'RWIND Simulation - License and Authorization' function in the "Help" menu.

    Figure 02 - License and Authorization Settings

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

  3. Check in the 'RWIND Simulation 1.xx Authorization Status' dialog box whether an active software key authorization is available. This is the case if the 'Software Key' option is selected in the 'Authorization Method' section, and an active authorization is indicated by a green dot in the 'Authorization Status' section.

    If the check turns out to be negative and a red dot is displayed, no RWIND Simulation license based on a software key is activated on the single-user computer. As a result, the activation period for a license cannot be extended.

    If the specified requirements are met, click the 'Extend Activation Online' button. The 'Renew Activation - Online' dialog box appears.

  4. The 'Renew Activation - Online' dialog box shows the license specification to be extended.

    Enter your online activation key based on your contract documents and define the new activation period in the date field.

    Then, start the online renewal with the function 'Renew Activation Now'

    This opens the 'RWIND Simulation 1.xx' dialog box.

  5. In the 'RWIND Simulation 1.xx' dialog with the confirmation prompt about the planned modification select 'OK' to finally change the activation period.

    After successfully changing the activation period, you receive a confirmation message and can use the program without restrictions.
Thus, your purchased license is used in our system for the newly defined activation period. 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.

To avoid unnecessary license assignments in our system due to unexpected computer problems on your part (defect, loss, hardware replacement, change of employees, etc.), we recommend keeping the activation period as short as possible.
