These issues affect the FMOD Unreal Integration for all versions of Unreal for the initial release of 2.01.12 and 2.02.03.

**Issues**

- No sound in packaged games.
- ContentBrowserPrefix error when upgrading from an older FMOD version.
- Linux libs are missing.
- Unreal Editor fails to launch on Linux.

**Solution**

- Re-download the affected packages. All affected packages have been fixed and are available on the download page with a “patch1”, “patch2” or “patch3” designator.
- If ContentBrowserPrefix errors persist or if Unreal Editor fails on startup, delete the ContentBrowserPrefix line from your DefaultEngine.ini (by using a text editor) and re-enter it using the Unreal Editor.
