Kontakt 8 VST3 plugin error in Ableton 12.1.10

Hi!

The VST3 version of Kontakt 8 is not showing i the plugin window in Ableton. The AU version is visible and working fine. After some usual trouble shooting (as reinstalling both Kontakt8 and Ableton) I found an clue in the Ableton Live PluginScanner.txt:

"VST3: check plugin at path: "/Library/Audio/Plug-Ins/VST3 Kontakt/Kontakt 8.vst3"
2025-03-04T13:51:47.493933: error: Failed to load plugin: a sealed resource is missing or invalid"

So Ableton sees the plugin but refuses to enable it.

I am in a middle of a big production and now I am stuck with missing plugin errors in my Ableton projects where I have used the VST3 Kontakt8. It will take a lot of extra work to update the tracks with the AU version and load the used sample libraries.

Any suggestion or could a Native engineer look into this?

    I am having the exact same situation with Komplate Kontrol…

    I'm on this version of Live and both are working fine in the VST3 version - try pressing alt/option while clicking on the rescan plugins button - this will reset the blacklist and force a full rescan

    Update: It seem like this is a Ableton issue and not NI. I have reinstalled Kontakt and the VST3 version is showing up in Presonus Studio One and working fine there. But in Ableton it is still the same sits. I should have reported this to Ableton support but I am on a tight deadline and have managed to work around the issue by replacing the Kontakte tracks.

    That’s why you need to do a reset rescan as Ableton has blacklisted it

    Hi every one!
    Thank you send me many message.
    I solved this problem with NI support

    ↓
    If the above does not solve the problem, please refer to the following document to completely uninstall Komplete Kontrol (especially make sure to uninstall the VST3 version).

    I have exactly the same problem. The VST3 version of Kontakt 8 was working fine in Ableton Live, I use it daily. Today went looking for the documentation for AR Vintage Drummer, and stared Native Access, and I saw 8 or 10 of the hundred or so NI libraries I own needed updates. I picked update all. Five minutes later I restarted Ableton and Kontakt 8 will no longer load. I reinstalled Kontakt 8 after completely uninstalling it, and it still doesn't work… the same error in the log.txt file as noted in the OP.

    Something happened in the update of Kontakt 8 that killed it in Ableton. I understand the VST3 might work in other daws (I can get it to work in Reason) - nevertheless the only change I did was update Kontakt. This feels like a NI bug, not Ableton.

    I'd like to add: This problem occurs in both Ableton Live 12 AND Live 11.

    It's not a bug - read above - the issue has been fixed for several users by forcing a rescan in Live - try alt/option + rescan to do a full rescan, if that doesn't work remove the VST3 then rescan, then put it back

    I was having this same problem specifically with the Kontakt 8 VST3, and this worked, but it's very important that you HOLD DOWN the OPTION key throughout the Ableton plugin rescan (speaking as a MAC user - not sure if this is the case on PC as well). Just holding the key when you press "rescan" and then letting go of it does not seem to get the job done.

    Thanks good point - as I have also said a further option is to remove the plugin from the plugin folder - deep scan - put it back and deep scan again, which seems to have worked for several users if all else fails.

    Obviously you could uninstall KK as someone has suggested but this shouldn't really be necessary as it effectively does the same as just removing and putting the plugin back but in a more laborious way.
