How to deactivate an authorized RWIND simulation license based on a software key on a single-user computer offline via email?


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 a different single-user computer), the license can be deactivated again offline via email 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 is 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 be deactivated.

    If the above requirements are met, click the 'Deactivation via E-Mail' button. The 'Deactivation of RWIND Simulation' dialog box appears.

  4. The 'Deactivation of RWIND Simulation' dialog box explains the deactivation process.

    Select the 'Deactivate RWIND Simulation 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.

    After successful deactivation, you will receive a confirmation message. You can use the program only in demo mode now.

    The dialog box 'Deactivation of RWIND Simulation' opens again.

  6. Deactivation code is now displayed in the ‘Deactivation of RWIND Simulation’ dialog box. Copy this text block to the Windows clipboard with the 'Copy to Clipboard' function and then paste the code into a blank e-mail with [Ctrl]+[V] or the Windows paste function. Send this email to to complete the license deactivation.

You can now reactivate the released license on another single-user computer.
