That does not look abnormal to me. iZotope doesn’t make it easy to install all of their software. It looks like you have one of the bundles. If you saved the installers. I Highly suggest that you always save a backup of all installers in a studio to a separate disk from anything else. It can save hours. But if you do, I suggest uninstalling and going through the installs again and making sure to only select the 64 bit VST3 option. That will give you the cleanest install for Cubase possible. There are a few of their products that are VST2.4 only, like Trash if I remember correctly.
Or if it doesn’t bother you, you can just leave it as it is. Look over in the Effects section or the Instrument section, and it is likely that there are non Blacklisted versions of all of the plugins you see in the image. In fact, there are likely multiple copies of those there. You can either go through and disable the older versions yourself, or reinstall iZotope plugins as discussed above.
from what i do remember, these file are not the plugin files but the program files from Izotope, from what i can remember i had a similar issue as well when i did install them on my system a while ago.
you should need to install these files to a different location and not into a location that will be also used from cubase to scan the plugins
and then also, like written before, ensure you only install the vst3 version and not the other formats
and then perhaps still, is a manual cleanup necessary
Yes, I’ve upgraded my PC to Windows 11 after the release of Cubase 12. Ozone 9 and all other iZotope plugins I own still work without problems with Cubase 11 and 12. Only few VST2 versions of them have been blacklisted. Their VST3 counterparts work properly.
Izotope is a different animal. I’ve spent a lot of time organizing my plugins and what I’ve learned about the Izotope product is that (in Windows) all the actual programs are stored here: This PC > Local Disk (C:) > Program Files > Common Files > VST3 > iZotope . These files/programs are .dll files that are triggered by .exe files found here: This PC > Local Disc (C:) Program Files > iZotope > (for example) RX 9 Audio Editor > win64 .
I think what you are seeing, noting the correct path (VST3) to the .dll file, is that you have also installed the VST2 .exe file. In your Blocklist pic, Cubase is telling you that Cubase will not open the VST3 .dll files using the VST2 .exe file.
