Ah, I've misunderstood how this works. I have updated OBS to the latest stable release, but my streamdeck software is still the one before the forced account creation which I refuse to use. I presumed the script would still check if the actual plugin can be updated, but I suppose the SD software needs to support it...
I am using my Stream Decks every day but don't have an account with Elgato. Then again, I haven't installed any new SD plugin in a long time and it seems that's what you need an account for now?
Does the older version still work for installing from the "shop" that was integrated into the application? If not, then there would be no difference to using the latest version without an account, as far as I can tell everything else is working here just fine (I am also not a fan of creating accounts everywhere). But if it does, you could temporarily install the older version (assuming you still have the old installer or it can be found somewhere) whenever you need to add a plugin, then afterwards install the new version again. That way everything is kept compatible.
Another thing you could try is install the newer SD version, have this script update your portable OBS to the newer SD OBS plugin, then install the older SD version again. I say chances are 50/50 that the older SD app is working with the newer SD OBS plugin, only one way to find out ;-)
Before you go through all of this hassle, have you checked out the Bar Raiders plugins? They can do everything with OBS that the SD base software can do and a lot more. And you don't get them from the shop but download their plugin .zip files from their Discord and install them yourself (obviously this means you need a Discord account though, but maybe you already have one anyway). They control OBS through its official websocket interface, which is why they don't need a plugin in OBS to be installed.
