8th Wall Remote For Unity Errors

Using the latest 8th Wall release 13.2 and Unity 2019.3.5f1 but Unity just throws a bunch of errors when I try to run the project with the 8thWall remote on ANdroid. Here is one of them...

H:/AndroidSDK/sdk/platform-tools/adb threw exception System.ComponentModel.Win32Exception (0x80004005): ApplicationName='H:/AndroidSDK/sdk/platform-tools/adb', CommandLine='devices -l', CurrentDirectory='', Native error= The system cannot find the file specified.

Any ideas how to solve this?

I am using Unity's recommended install settings for all the JDK,SDK,NDK etc...and I also installed the iOS built target stuff which I heard I needed too (even though I'm not using that).

Cheers
