Free trial


Polysun is regularly updated. Updates do not only refer to catalog data but also to software functionalities that are constantly extended. It is therefore advisable to always keep your Polysun updated to the latest version.

Users are entitled to free updates if they first picked-up their license or their latest subscription expired less than twelve months before. If your license has expired, you will be informed by an appropriate message. Renew your subscription or contact your distributor.

Choosing Look for updates in the first line (after Polysun has been started) under Display in the settings of the Options menu Polysun automatically checks for updates on the server. All you need is a working Internet connection. 

If an update is available a message is displayed to inform the user. Proceed as follows:

  • Download the update and close Polysun.
  • Start the downloaded Polysun installer.
  • Follow the instructions of the Polysun installer.
  • If you have more than one Polysun installation, make sure the correct installation path is selected.

For further questions, please do not hesitate to contact your distributor.
