This is probably because we also require riscv32-esp-elf-gcc for ESP32-S2 and ESP32-S3 (due to their RISC-V ULP coprocessors), but the installer currently doesn't install riscv32-esp-elf tool for ESP32-S2 and ESP32-S3.

(This was also mentioned in #158 (comment).)

anyway, I manage finish install ESP-IDE by

1. download xpack-riscv-none-elf-gcc-12.2.0-1-win32-x64.zip and put it into Espressif\dist\
2. select [esp32-c3] (basically leave everything default)

I don't konw which option works, but it worked.

I highly suggest download extra package from espressif.com or make offline installer truly offline, we don't really mind a bigger installer package.

Thank you @mzhboy for reporting the problem with the installation.
We were able to simulate the problem.

Suggested workaround: Check ESP32-C3 checkbox.
