PhysX 5.6 builds fine, Blast and Flow builds fail.

Hello,

Very simply, latest PhysX builds nice and easy.

Blast build fails here. This winsdk is no longer available, this perhaps needs to be updated?

Package **'winsdk' at version '10.17763' is missing from local storage.**

Meanwhile Flow build fails like so:

!!! Failure while building nvflow !!!

Is this known, or is there something about my environment setup that I didn't get correct?

Thank you.

Hey @kingc8 , I can confirm the issue you mentioned. The winsdk package (version 10.17763) was indeed missing earlier, but I’ve made the necessary change on my end and it’s now available again. Please make sure to download a fresh copy of the repo and try building again — that should resolve the problem. Let me know if it still doesn’t work for you!
