I'll run through what this entire section's intention is.
In the first instance, where a software company or otherwise is intending on seeking express consent for a download of a computer program onto a user's computer, they have to seek the requirements that are under subclause 10(2). At that time, should that computer program do anything listed in the activities of subclause 10(2.2) under clause 10, they have the additional requirements of subclause 10(2.1), which is notably apart and separate from a licence agreement:
(a) describe the program's material elements that perform the function or functions, including the nature and purpose of those elements and their reasonably foreseeable impact on the operation of the computer system; and
(b) bring those elements to the attention of the person from whom consent is being sought in the prescribed manner.
Further, an exception to that is subclause 10(2.3) in the case where it is for the reasons of transmitting the message, i.e. “transmission data”, or where it performs other operations that might be specified in regulations. They are excepted.
For computer updates and upgrades, as long as it does not do anything that's listed in subclause 10(2.2), they do not have the additional requirement. Again, it's the same for the list in subclause 10(2.5). As long as it is not doing anything in subclause 10(2.2), they do not have the additional requirement.
That, hopefully, describes the entire consent regime around the installation of a computer program.
