cannot add MACD_Sample_1.mq4

 
Hi ! I followed instructions at
'Automated Optimization of a Trading Robot in Real Trading'
Automated Optimization MACD

I am using Alpari MT4.

mq4 was compiled with one error.
'auto_optimization.mqh' - cannot open the program file D:\Program Files\MetaTrader - Alpari UK\experts\MACD_Sample_1.mq4 (38, 1)


Pls advise what to do.
