Hi,
Congrats on the new version and thanks for the awesome work.
When I try .\repo.bat install_usdex --version 1.2.0, I get the following

Package 'usd-exchange_usd_24.08_py_3.10' at version '1.2.0+windows-x86_64.release' is missing from local storage. [08/01/25 17:27:00] ERROR ConfigurationError exception stack trace dumped to logfile log.py:182 C:/g/usd-exchange-samples/_repo/repo.log. Stacks dumped to console via --verboseor--tracebacks. ConfigurationError: Unable to download usd-exchange_usd_24.08_py_3.10, version 1.2.0+windows-x86_64.release

I can't figure out a solution but seems the package usd-exchange_usd_24.08_py_3.10 is not found on the remote. Do you know a way around ?

Thanks for your help

Hi @thiistephane thanks for the quick bug report! I can reproduce this on my side too. There seems to have been a glitch when the packages were uploaded to S3.

I was able to install that same version on Linux, its only the Windows package that is missing currently. I will try to re-sync with S3 and see if the issue resolves. In the meantime, you have a couple options:

• Some other flavors do work for me. e.g. .\repo.bat install_usdex --version 1.2.0 --usd-version 25.02 is working. So if you are not strictly tied to USD 24.08 you can choose any of the other flavors (.\repo.bat install_usdex --help shows all valid choices).
• Similarly .\repo.bat install_usdex --version 1.2.0 --python-version 3.11 is working for me, so if you need USD 24.08 but can move to py3.11 that is another option.
• You can also build from source rather than install the prebuilt binaries package.
  • .\repo.bat build should produce the same things you would have gotten in the packages (plus a bit more than you need for runtime, which you can delete).
  • Note this release was from production/1.x not from main, so you need to switch branches before building. See our contributor guide for more tips on building from source.
• Switch to Linux & use ./repo.sh install_usdex --version 1.2.0 😉 🐧
• Wait ~24hours for S3 to re-sync & try again with the default flavor of USD and Python.

Sorry for the trouble!

It looks like the re-sync has completed now, and I am able to .\repo.bat install_usdex --version 1.2.0 on Windows.

Let me know if its working for you as well.
