Why I have to re-download after failed to install isaac sim?

I was using the omniverse-launcher in ubuntu to install Isaac-sim, after downloaded nearly 6.31GB files, the installation stuck due to some pip install error, but when I want to reinstall Isaac-sim, the omniverse-launcher still need to re-download that 6.31GB files. I want to know is it normal or is it a bug?

Hi @Te77iiiii_Ho - I understand your frustration and have raised the question to the respective team. I will let you know as soon as I hear back from them.

Would like to ask if this issue has been resolved? What should I do, I’m experiencing the same thing.
thanks!
I stop the download and then re-click and it gets stuck as well.

Hi. Do you see the same issue when installing Isaac Sim 4.0.0?
