You can't execute all the updates at the same time because the updating process assumes you are upgrading from version to version and every update you perform is based on a specific version of a dll/executable etc. If you try and launch all the updates and for example, your program has version 1.1.1 and one of those updates brings your program to 1.3.0 but in order to reach that version you have other update packages which is specific to 1.1.1 then launching the update for 1.1.1 and 1.3.0 will simply not work or make your software unusable. It's not recommended to launch all the updates in one single launch of the files.
