Hi Andrian,   
  
Thank you for contacting Syncfusion products.    
  
The reported error may occur if the Syncfusion.WebKitWrapper does not have read/write/execute permission. Kindly allow the WebKit wrapper file to executing the file as a program to resolve the reported issue. Refer below screenshot and KB link for more details,
