Not sure what you are doing or what is not working.
Just remember these are incremental updates, not cumulative updates, so you need to install all updates 9.3.1, 9.3.2, and 9.3.3.
I am doing similiar steps to this:
But when I run the install after slipstreaming, I either get an error about another version already installed or if there is no such installation of adobe, then it will just install 9.3.0. I have done these steps several times and always the same results.
