I have downloaded the ST4 version of OTONE. Extracted all the parts to the correct folders in the "SampleTank 4" directory. I'm sure I've done that part right, because clearly, SampleTank recognizes the patches. However, when I try to load the patches, I get the above popup. I can't authorize SampleTank 3 because I don't have it, and it is not offered. I have also tried to use the ST3 version of OTONE to the same result.
Notice that the OTONE patches are greyed out.

Also, these "Imported" Libraries have these icons on them. When I click on "ST4 Imported" it simply brings me to the IK My Products page with no further instructions.

Somehow I've not seen a single other post about this issue. Can I get some help?
Unfortunately I don't know how can I help more from my side on this issue. Seems like you have to import at least one sound from S3 free library to authorize anything built for that version - orchestools one included. I have in my plans to make a proper sample4 version of the library using their new S4 editor which is way more powerful than S3 - but it will require building everything from scratch and that's a lot of work. It might be available early 2023 and it will be cheap to purchase but it wont be free. You might want to try ORCHESTOOLS | SECTIONS though. I personally think it is way more powerful and it is in constant development, version 1.5 which will be released by the end of this year will have more sounds and possibilities, and more planned for 2023 and beyond!
