Below is example error happen at Sales Invoice
01. Click Tools | DIY | SQL Control Center...

03. Look for the script like function GetTaxedValue(AValue: Variant; lTaxRate: string): Variant;. Something like above
04. Change all to below new script

function GetTaxedValue(AValue: Variant; lTaxRate: string): Variant;
var lStrLst: TStringList;
    TaxRate, S: string;
    I: Integer;
begin
  Result  := Null;
  lStrLst := TStringList.Create;
  TaxRate := DataSet.FindField('TaxRate').AsString
  try
    try
      lStrLst.Delimiter := '&'; 
      S := Trim(StringReplace(TaxRate, '+', '&', [rfReplaceAll]));
      lStrLst.DelimitedText := Trim(StringReplace(s, 'E', '', [rfReplaceAll])); 
      for I := 0 to lStrLst.Count - 1 do
      begin
        S := Trim(lStrLst.Strings[I]);
        if S[Length(S)] = '%' then
        begin
          S := Trim(Copy(S, 1, Length(S) - 1));
          AValue := AValue * ((100 + StrToFloat(S)) / 100);
        end
        else
          AValue := AValue + StrToFloat(S);
      end;
      Result := AValue;
    except
      RaiseException(ExceptionType, 'Tax Rate formatting error ');
    end;
  finally
    lStrLst.Free;
  end;
end;
