[Unity] Wwise Launcher doesn't allow to add the Xbox One integration.

Question

Hello,
We've met with the pretty strange behavior of Wwise Launcher.  We're trying to add the Xbox integration to our Unity project (which already has integrations for Windows, Mac, Linux, and PS4), but Wwise Launcher can't proceed further after checking the Wwise project file and the SDK folder. We get the following error: "Not all the platforms selected above are currently installed in Wwise. The missing packages will be automatically selected for you. Please make sure to add any plug-in that you wish to use in your project."

Then it suggests modifying Wwise installation, but we can't do that since our Wwise already has everything it needs: the plugins and the platforms were added during the installation. So, there's nothing to modify, but still, we can't add the integration we need.
How we tried to solve this:

1) Just to be sure, we did a fresh Wwise install on a separate computer and selected all plugins/deployment platforms. We also checked manually that packages are placed in the SDK folder. After that, we tried to add the Xbox integration and got the same error.
2) We tried to add the Xbox integration to an empty Unity project. Got the same error.
 

The latter is especially strange.
Is there anything that could help us? At the moment, we can't build our Xbox build until it has Wwise working, and Wwise doesn't really want to be integrated (without telling us any specific details like what EXACTLY it needs).
Our software:

Unity: 2018.1.0f2 
Wwise: v2016.2.6.6153
Wwise Launcher: v2019.6.0.914

Thank you in advance.

P.S. we tried to add Wwise 2019.1.2 Xbox One integration to an empty Unity project and it worked as intended.

Answer 1

We had a similar problem when trying to upgrade the Wwise version our Unity project is using. What we had to do was to install the SDK, since we didn't install it because we thought it wasn't necessary (actually, the Wwise Launcher explicitly states that the C++ SDK is not necessary for Unity development). After installing the SDK, we could proceed.

Thank you, Francisco, but we have SDK installed for all possible platforms. :(

I found the solution. Somehow, if you copy the SDK folder somewhere else and select it as the source, Wwise Launcher just warns you about not pre-installed SDK but allows you to start the process. Finally added the Xbox One integration.
