Sometimes when processing the orders the system raise the error message "Method not found: '!!0[] System.Array.Empty()". This occurs because of the .NET framework mismatch.


Please install the .NET Framework version 4.6 or above.


Currently TOE has .NET framework 4.7.1 . So it is recommended to check whether the customer too has the same version on their machine. If not install it.
