ESU MAK is 3 years for all editions but they can choose to exclude some editions after 1st year, we can only wait and see
The shown error in the screenshot is not from the uup dump ISO creation, it is an install error. Then it probably is not UUP related, test with updated MVS ISO.
With these there are no errors during installation, it is the 3rd compilation of uup that I receive the same error in install.wim, during the installation process, I am never criticizing, I am just reporting because I use upp dump a lot. NOTE. the test was done on more than one machine and more than one iso.
You said you didn't notice errors during conversion: So, if there were errors during the conversion, please post the full progress here in code tags.
It is only possible to see the error during the installation process, when creating the script there are no errors.
And still i would like to see the full conversion progress. And start at least with the exact build (from what download at uup dump) and settings (convertconfig.ini).
By having mvs ready there is no need to compile it now, next time I will prepare everything and send it here to you, I believe there is no need to keep modifying convertConfig.ini as it should already be the default configured for creating the iso, although it is always good to find an error. Sorry, I use a translator, there may be misinterpretations, I'm not to judge, but to help.
Already asked him about it, this was happening before, that's why i always ask for full progress to be shown, there is more to conclude from it, even without errors
