How to fix Wwise Launcher Error - Syntax Error: Unexpected string in JSON at position 11590?

Question

Hi there,

After installing the Wwise Audio Lab sample project, I now can't open the Wwise launcher at all, and I get the following error message:

 

"An error occurred. We are sorry for the inconvenience.

If you were in the middle of an installation, please restart the Wwise Launcher and try again.

I've uninstalled and re-installed the launcher to see if that would fix it, but the same error message pops up when I try to open the launcher again after a fresh install.

If anyone at all can help, I would massively grateful it as I don't know what to do.

Thank you.

I suggest you reach out to our Support team (https://www.audiokinetic.com/customers/tickets), we will probably need for you to provide some configuration files in order to understand the problem and unblock you.

Hi Samuel - as this is the Wwise Launcher, how should I register it as a product so I can get support, should I go through the Non-Commercial option?

Going through a project Support Ticket would be the way to go.

(Posting answer here for others experiencing the same issue)

This error occurs when the file keeping track of Wwise installations is corrupted.
We have received other reports of this issue and are working to mitigate this issue.

The only workaround to this issue requires deleting the install-table.json file located in:

• Windows: C:\Program Files (x86)\Audiokinetic\Data\install-table.json
• macOS: /Applications/Audiokinetic/Data/install-table.json

Be aware this will clear out the list of installed packages that the Launcher knows about. Once the Wwise Launcher no longer reports this error, you can use the "Locate local copy of Wwise" and "Browse for project" from Unity/Unreal Engine tabs to repopulate the lists.
Note that the list of installed plug-ins and platforms for a Wwise version will not be discovered when locating a local copy at the moment. For this reason, we strongly suggest to re-install the versions you require if you are going to modify an existing installation.
