I recommend to always carefully read the release notes files.
Version 3.0.0 is initial version supporting AUTOSAR R21-11 without Crypto drivers.
Package QLP01 should be installed on top of this version. It contains AUTOSAR R21-11 Crypto driver.
Version QLP02 is intended for customers who require Autosar version 4.4. This contain all the modules except Crypto. QLP03 contains Crypto module for Autosar 4.4 and it should be installed on top of QLP02.
Version QLP04 is another “base” installation (like initial 3.0.0 or QLP02) and the main difference is that it adds support for S32K116V, S32K118V and S32K144N 3.3V devices.
Version QLP06 just adds support for S32K142N 3.3V devices and it should be installed on top of QLP04.
All these details can be found in the release notes.
Regarding the installation – install only relevant packages. For example, version 3.0.0 and QLP01 on top of that. Or QLP02 and QLP03. Or QLP04 and QLP06. Don’t mix them together, always follow the instructions in the release notes files.
If you install, for example, QLP02 over 3.0.0, this is considered as upgrade and older version is removed. That’s the reason why you can’t see examples from older version.
If you need more version of RTD, recommended workaround is to install more instances of S32 Design Studio.
