Please, be aware that I am only describing ways to update the software. Thus, I am not considering the procedures to setup an initial installation. I already explained that at the beginning of my first post:
"We have only covered incremental software updates. We have therefore not included on this list the methods of update through a new project installation or through the creation of a new flash memory. "
May be I am wrong, but I think that before AR 4.33 this way of creating “minor updates” on an USB pen drive was not available.
