How can I online deactivate an authorized RWIND Simulation license based on a software key on a single-user computer?


The RWIND Simulation program is protected against unauthorized use. The application works without restrictions on the single-user computer on which the software key-based license is activated. To release the assigned license (e.g. for use on another single-user computer), the license can be deactivated online again on the license-holding single-user computer. To do this, proceed as follows:

  1. Run the 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.

    Figure 03 - Authorization Status

    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. Consequently, no license can also be deactivated.

    If the above requirements are met, click the 'Deactivate Online' button. The 'Online Deactivation' dialog box appears.

  4. The 'Online Deactivation' dialog box shows the license specification to be deactivated.

    Select the 'Deactivate Now' function.

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

  5. In the 'RWIND Simulation 1.xx' dialog box, select 'Yes' for the license deactivation confirmation dialog box to permanently deactivate the license.

    After successful deactivation, you will receive a confirmation message. You can use the program only in demo mode now.
You can now reactivate the released license on another single-user computer.
