Method 2: Create TelemetryKeyword.ws File

If the method one didn’t work for you and if you are still facing the script compilation error, then try method 2. Here we will be creating a telemetrykeyword.ws file and copy to the Scripts\engine location.

Open a text editor such as Notepad ++ and copy the code given below.

/* Copyright © CD Projekt RED 2015 */ import class CR4TelemetryScriptProxy extends CObject { import final function Log( eventType : ER4TelemetryEvents ); import final function LogWithLabel( eventType : ER4TelemetryEvents, label : String ); import final function LogWithValue( eventType : ER4TelemetryEvents, value : int ); import final function LogWithValueStr( eventType : ER4TelemetryEvents, value : String ); import final function LogWithLabelAndValue( eventType : ER4TelemetryEvents, label : String, value : int ); import final function LogWithLabelAndValueStr( eventType : ER4TelemetryEvents, label : String, value : String ); import final function SetCommonStatFlt( statType: ER4CommonStats, value : float ); import final function SetCommonStatI32( statType: ER4CommonStats, value : int ); import final function SetGameProgress( value : float ); import final function AddSessionTag( tag : String ); import final function RemoveSessionTag( tag : String ); import final function XDPPrintUserStats( statisticName : String ); import final function XDPPrintUserAchievement( achievementName : String ); }

Now save the file with above code as telemetryKeyword.ws.

Now move the telemetryKeyword.ws file to \content\content0\scripts\engine.  telemetryKeyword.ws file to \content\content0\scripts\engine.

Alternatively, you can also directly save the file to this folder location. If you don’t know where to look for these folders, then you should find it in Witcher 3 installation folder. Now run the game and see if the script compilation error in Witcher 3 has been fixed.
