I don't know what error number 522 exactly means, but I suspect that you are trying to install a Nucleus version that is more recent compared to want is found in the license file. Typically customers will receive product updates as long as they are under maintenance. E.g., a license like "INCREMENT ideaarch64elf mgcld 2016.100 24-oct-2020..." only allows to install and use certain CodeBench features released before November 2016. But the license itself is valid until 2020. So make sure you only install Nucleus ReadyStart versions that comply with your license or reinstate your maintenance contract to be able to install the latest product version.
