Hi Maciek,
Our licenses can be backward compatible but not forward compatible. For example, you can use the license for v11.1 with the installer of v10.6 but you can't use the license of v10.6 with the installer of v11.1.
In this case, for you to have access to the v11.1, you will need to renew your technical support maintenance contract. Remember that our perpetual products are permanent but it comes with the first year of the tech support contract. After that first year, you will only have access to the versions released until that date permanently. With this being said, your product tech support contract expired back in 2014, so this is why the v11.1 is not offered until its renewed.
For more details about this and how to renew, please check or Licensing and Registration FAQ here https://www.nxp.com/design/software/development-software/codewarrior-development-tools/licensing-and...
Best Regards,
Paulina
