@mfialaf The feature for selecting targets was added to the installer. You can test by installer from Releases https://github.com/espressif/idf-installer/releases/tag/online-2.10-beta-03

The problem is that when only specific target is installed and tools for other targets are missing, the activation shell displays warning and refuses to initialize. Here is example of installation only ESP32-C3:

ERROR: tool xtensa-esp32-elf has no installed versions. Please run 'C:\Users\User\.espressif\python_env\idf4.4_py3.8_env\Scripts\python.exe C:\Users\User\Desktop\esp-idf\tools\idf_tools.py install' to install it.
ERROR: tool xtensa-esp32s2-elf has no installed versions. Please run 'C:\Users\User\.espressif\python_env\idf4.4_py3.8_env\Scripts\python.exe C:\Users\User\Desktop\esp-idf\tools\idf_tools.py install' to install it.
ERROR: tool xtensa-esp32s3-elf has no installed versions. Please run 'C:\Users\User\.espressif\python_env\idf4.4_py3.8_env\Scripts\python.exe C:\Users\User\Desktop\esp-idf\tools\idf_tools.py install' to install it.

I assume that this is not expected bahavior.

The problem is caused by missing --targets= before list of targets in command https://github.com/espressif/idf-installer/blob/feature/target_selection/src/InnoSetup/Environment.iss#L409
