# Changes in licensing of the software "TOPODRONE Post Processing"
TOPODRONE announces significant changes to the licensing system for its TOPODRONE Post Processing software from 01.06.2023. As part of these changes, licenses will now be issued as activation keys, which will significantly simplify the process of obtaining and activating the software.
With the introduction of the new system, customers will no longer be required to use their personal account to activate the program. TOPODRONE Post Processing is now activated by entering the key in the appropriate field on the screen. This activation method makes the process more convenient for users, as it allows them to avoid additional steps related to account management.
However, successful activation of the software will still require access to the Internet. This is necessary to verify the validity of the entered key and to confirm the license, which ensures licensing compliance and protects the software from unauthorized use.
TOPODRONE is confident that these changes will not only improve the user experience, but will also make the activation process more intuitive and faster. We want users to be able to focus on their tasks, not the hassle of managing licenses. With the new activation system, TOPODRONE Post Processing will be easier to use and communication with the program will be more efficient.
Now all distributions are in [TOPODRONE Software Distributor](https://file.topodrone.com/TOPODRONE%20SD.exe)
