Hi,
There are a couple of things that you can check:
Firstly check `fmodstudio` file exists in your Unity Project files here:
If it is not there please let me know.
If it is there then check the import settings for `fmodstudio` looks like this
You can open this window by clicking on the `fmodstudio` file.
Hope this helps!

The `fmodstudio` file does exist and the import settings are the same as the screenshot.
Could the problem be from updating Fmod “2.02.03” to “2.02.07”?
I deleted the “Fmod” folder from the “plugins” folder before updating so I’m not sure if I should have done it differently.

Hi,
No worries, let us try re-importing one more time.
When re-importing the package make sure to select the “All” option as this will select anything you are missing. Hopefully, the FMOD Setup Wizard will pop up, if not it can be opened from the FMOD drop-down menu along the toolbar of Unity. The setup wizard will prompt you to “Disable Existing Native Libraries”, follow the prompts and restart Unity. Again the FMOD Setup Wizard pop-up again, now prompting you to “Copy New Native Libraries” follow the prompts and finish the Setup Wizard to ensure FMOD is set up properly in the Project.
Hopefully this helps!

Was any solution ever found to this? I have exactly the same issue and all file and settings are correct as shown above but every time I restart unity it cannot find a dll and I need to re-import FMOD.
