Is it safe to upgrade windows 11 (pro)to 22H2 or will it break anything in Houdini?

Thank you

This may be purely coincidental, however having updated to 22H2 the License server is not running so unable to have Houdini boot up.

Anyone else having problems (before I upgrade lol)

Can anyone from SideFX please comment?

Whether you're upgrading from 10 to 11 or just installing the latest update for 11, it's fine. We generally don't comment on specific updates for an OS. If the minimum version of the OS is on our system requirements page, you're generally good to go.

I've installed that update on my work and home pc's and nothing's melted yet.

Installed and confirming that so far so good. I was getting some acio could’ve be loaded pop ups but reinstalled latest daily build and works like a charm. I mean as much charm as one can have on windows lol

Very strange, in a positive way. Just tried again and no concerns re License server error messages that I was having and Houdini is up and running. Relieved +++
