  • Answer

    The RWIND Simulation program is protected against unauthorized use. Before you buy the program, you can use a limited trial license to test all program features before the purchase. After this trial period, the program switches to a limited demo mode and deactivates the function to activate a new trial license. If you indicate a justified reason, the program can be authorized again with a temporary trial license via the e-mail activation.

    For this, proceed as follows:

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

      Figure 01 - Program Start
    2. Click the "Activate Now" button to confirm the authorization check.

      Figure 02 - Authorization Check
      Then, the "RWIND Simulation 1.xx Demo Authorization Status" dialog box appears.

    3. In the "RWIND Simulation 1.xx Demo Authorization Status" dialog box, select the "Software Key" option in the Authorization Method area and click the "Activation via E-Mail" function in the lower part.

      Figure 03 - E-mail Activation
      This opens the "Activation by E-Mail" dialog box.

    4. In the "Activation by E-Mail" dialog box, enter the license number 1111 as well as the name and address of your institution under License Information.
      Furthermore, enter a user-defined description of the workstation to be activated under "Description of Workspace" and the RWIND Simulation level with an expiry date of the activation to be carried out under "Required Authorization."
      Then, click the "Generate Request Code" button to confirm your entries.

      Figure 04 - Generating Request Codes
      The "RWIND Simulation 1.xx Demo" dialog box appears.

    5. Check the data entered in the "RWIND Simulation 1.xx Demo" dialog box. If they comply, click "OK" to confirm the dialog box.

      Figure 05 - Checking Entries
      This opens the "Activation by E-Mail" dialog box.

    6. The "Activation by E-Mail" dialog box consists of three parts. In the "Step 2" tab, the required request code is displayed on the left. Copy this text block to the Windows clipboard by clicking the "Copy Request Code" button and then paste the code into a blank e‑mail with [Ctrl]+[V] or the Windows paste function. Send this e-mail to support@dlubal.com with the justified reason for a new trial period for further processing.

      Figure 06 - Sending Request Code
    7. You will receive an activation code from us. In the dialog box, go to the "Step 3" tab and enter this code in the "Activation Code" text box.
      Then, click the "Activate Now" button to run the activation process.

      Figure 07 - Program Activation

    After the successful authorization, you receive a confirmation message and can test the program for the specified trial period without any restrictions. After the expiration of the trial period, the program automatically switches to the limited demo mode.

  • Answer

    If using a real computer with the Windows operating system and there were no hardware changes and/or new installation of the operating system, the license problem is usually caused by the following:

    • The mandatory service "Sentinel LDK License Manager" may be damaged after a Windows update.
    Solution: Reinstall the driver. You can download and install it under the following link. http://download.dlubal.com/?file=Sentinel_LDK_GUI_setup.zip

    • The antivirus program blocks the hasplms.exe file.
    Solution: Add hasplms.exe from the directory to the exceptions of the antivirus program.

    • Other security software (for example, Sandboxie) prevents proper communication of the license service.
    Solution: You can either add hasplms.exe to the trusted programs or uninstall this software.
  • Answer

    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 the demo mode; the previously used license is freely availablea gain for a new activation. To avoid the reactivation on the same single‑user computer, it is possible to renew the license online (a computer is connected to the Internet) by specifying a new activation period before the activation period expires. Proceed as follows:

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

      Figure 01 - Program Start

    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 if 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. As a result, the activation period for a license cannot be extended.

      If the requirements mentioned above are met, click the "Extend Activation Online" button. The "Extend Activation Online" dialog box appears.

    4. The "Extend 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, click the "Extend Activation Now" function to run the online extension.

      Figure 04 - Extension of Activation

      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, click "OK" to finally change the activation period.

      Figure 05 - Confirmation Prompt

      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, employee change, and so on), we recommend you to keep the activation period as short as possible.

  • Answer

    The RWIND Simulation program is protected against unauthorized use. The application works without restrictions on a single-user computer, where the license based on a software key has been activated. To release the assigned license (for example, to use it on another single‑user computer), you can deactivate the license on the license-holding single-user computer offline via e‑mail. Proceed as follows:

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

      Figure 01 - Program Start

    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 if 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. As a result, no license can also be deactivated.

      If the requirements mentioned above are met, click the "Deactivate 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.

      Figure 04 - E-mail Deactivation

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

    5. In the "RWIND Simulation 1.xx" dialog box, click "Yes" to confirm the license deactivation.

      Figure 05 - Confirmation Prompt

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

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

    6. The 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 support@dlubal.com to complete the license deactivation.

      Figure 06 - Sending Deactivation Code

      With this code, we document a proper deactivation in our system.
    You can now reactivate the released license on another single-user computer.

  • Answer

    If there is no authorization file already being used on the computer, the program tries to reactivate the softlock. Since this is already active, the corresponding message appears. There are two ways to apply the already activated license to the clients.
    1. Select the "Use demo version" option in the "Authorization" dialog box and load the authorization file as follows: Help → Authorization → Load Authorization File
    2. Rename the AUTHOR.ini file to AUTHORE.ini and save it in the directory C:\ProgramData\Dlubal\Global\General Data.
