How can I authorize the trial version of RWIND Simulation on a single‑user computer?


The RWIND Simulation program is protected against unauthorized use. Before you purchase the program, you can use a limited trial license to test all program features before the purchase. 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. 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, click the 'Activate Trial License' function in the lower part.

    This opens the "Trial License" dialog box.

  4. The "Trial License" dialog box describes three steps. Follow these steps from 1 to 3.

    Open the website in Step 1 with the "Request Activation Code" function and click "Submit Request" to confirm the form filled with your contact information.

    Subsequently, you will receive an e-mail with an activation code to the specified e-mail address. Enter this code into the empty text box in Step 2. In Step 3, activate the temporary test mode using the "Activate Trial License" function.

After successful authorization, you receive a confirmation message and can test the program for the specified test period without restrictions. The program automatically switches to limited demo mode after the trial period has expired.
