I am having the same problem that you did but when I try your solution I get a message stating that the MT4 directory is not valid. I have been trying to find a solution for ages, but I just can’t get it to work! Does anyone have any idea what I am doing wrong?
This is just before I press the OK button

and then the message I get after pressing OK:

Any help would be appreciated.
