In the Acustica Audio\Framework folder there are two folders – Framework-Official and Framework-R2R. You can copy any folder of your choice (later it will be clear where to copy). The difference is that the Framework-Official folder contains the official files, while the files in the Framework-R2R folder have been edited by R2R. Personally, I copied the files from the Framework-R2R folder and followed the experimental path. Everything works great. All the best!
