We bought a new perpetual license of LabVIEW for our VIA a few months ago. It worked just like the old one. I was able to add it to the VLA software, then create disconnected licenses for my users, or machines. The discount offered was frankly way more than we were expecting. It wasn't in the budget this year, but my manager was able to push it through. When this year is up, we will look into if it makes financial sense to purchase another year or not. I think we skipped 3 years of software buying, so upper management was happy to have saved those years in software cost, and am grateful we didn't take NI up on their offer to get a locked in price for 3 years on the subscription model.
Oh and as for Windows 11, it doesn't have to be all bad. We have a set of software that gets installed on a base Windows 11 that uses OpenShell to bring the start menu back, ExplorerPatcher, and a couple WinAero Tweaker settings to do things like have the normal context menu, bring paint back, set remote desktop, and various other things people are used to. None of my users so far have realized it isn't Windows 10. These tweaks shouldn't be necessary, but at least there is options to make it better.
