You should download the a zip of the whole github tree (at the version you need) and runthe installer (`install.bat [esp32[,esp32s3]]` from there. Some Windows version (at least) have now a SSL certificate issue. You can workaround this by editing idf-tools.py and adding the following under ìmport ssl`
+```
+import ssl
+ssl._create_default_https_context = ssl._create_unverified_context
