Transfer a license

When you activate your PVsyst copy, the license is paired with the computer hosting PVsyst. Therefore, you can not use this license on another computer at the same time.

However there are some cases when you would like to switch to another machine. There is a way to use PVsyst on another machine, this is called license transfer.

Warning! The number of license transfers is limited to four over a period of 30 days starting the date of the first transfer.

How does a transfer work ?

A license transfer requires two steps to be complete :

  1. The license must be deactivated on the the first computer
  2. The license must be actvated on the second computer

How to transfer from computer A to computer B

  • Start PVsyst on computer A.
  • In main menu go to License
  • The license description appears, click on the Transfer button.
  • To avoid unwanted transfers you have to enter your Customer ID and click on the OK button.
    • Success: if deactivation went well you will see a success message, then you can close the transfer dialog. Computer A is now in demo mode.
    • Error: if deactivation failed you will see an error message. Contact us if the problem persists. If it is a communication error, see below.

Deactivation fails because of a communication error

It could happen that PVsyst can not connect to the license server because of an internet configuration issue. In this case, PVsyst will ask you to perform the deactivation manually through an external web browser.

  • Accept the notification about performing deactivation through an external web browser, this will deactivate PVsyst from the current computer and then show you a validation link. Computer A is now in demo mode.
  • Click on the validation link (it will open the default web browser), or copy-paste it to a web browser (it could be on another computer).
    • In the web browser, follow the instructions (basically all fields are already filled with correct values, you just have to validate the captcha).
    • Then click on Deactivate license.
    • Success: if deactivation validation went well you will see a success message.
    • Error: if deactivation validation failed you will see an error message, contact us.
  • Start PVsyst on computer B.
  • Follow the activation procedure using the same activation key (35 chararacters) you used to activate computer A.
