Hi Samuel,
Thank you for the response. I've checked the Unity project's Assets folder, but I don't appear to have the Deployment folder in the Assets\Wwise location.
In the Unity tab of the Wwise Launcher, I clicked 'Modify Wwise in Project'.
I then clicked 'Modify Wwise 2021.1.4.7707'.
I made sure Google Resonance and Mastering Suite were enabled on the next screen, and then after proceeding, the 'modify operation completed successfully' text appeared.
I then went back to the Unity tab of the Wwise launcher, and clicked the bottom Modify button. After clicking modify, the applying operation progress bar hung on the creating working copy notice for a long time, before then eventually getting stuck on "Executing Unity to complete the installation" notice (30+ minutes). This operation never completed, and in the end I had to force-quit the Wwise launcher.
A WwiseIntegrationTemp folder was made in the process, but as the 'Executing Unity' progress bar didn't complete, this did not get automatically deleted.
What do I need to try next? I'm really confused and not sure where I'm going wrong
