O tom se nikde nepíše, takže IMHO i do firmy. Je to prostě normální licence, akorát nezahrnuje možnost upgrade na vyšší verzi. Přepis mailu, co posílají po odeslání registračních údajů (id zcenzurováno):

Dear User,

Thank you for filling out our small questionaire.

In order to receive your license key file for the WinRAR 3.51 non upgradeable
version, please click on the following link or copy and paste this link in the
navigation/address bar of your Internet browser:

http://www.win-rar.com/bestoverallutility/download. php?id=xxxxx

IMPORTANT: You only have two attempts to download the key using this link.

The download contains a RAR archive, including your license key. Please SAVE
this archive to your disk. By opening it with double click on it's icon, WinRAR
registers your version automatically and you get the information:

"Correct registration: Thank you for support".

For further information please read the readme.txt

Please remember that your license key file is valid for the WinRAR 3.51 non
upgradeable version of WinRAR only. We recommend making a backup copy of your
key file as soon as you receive it. Although we can recover lost keys, there may
be a small charge and delay involved in recovering any lost key files.
