PDF-Reports will show the entered company name, e-mail address and telephone number as well as name and address of license holder.

In case of relocation the license holder’s address can be changed collecting the license again (see paragraph Add license).


A variety of settings can be adjusted here including the automatic search for updates, the display of Tool Tips, language, units and currency.

Add License

Should a license be added or renewed, e.g. after your Polysun subscription has been renewed, user-ID and e-mail address should be entered here like when the license was first released. Review your information for accuracy on the ensuing page. It is important that the entered information is correct as it will appear on all reports and your license will be registered using such information. Collect your license again and edit your information if you have relocated or changed your e-mail address.

A working Internet connection is required to collect the license. Ensure that the same network cards are always activated (possibly not a wireless network-card) when collecting your license and operating Polysun.

Subscription / Upgrade

If your Polysun subscription has expired or your wish to upgrade your Polysun (e.g. from Professional to Designer) here, you will be able to order all required products. Do not hesitate to contact your distributor any time. When your subscription has been renewed you can renew your license under Add license.
