I solved one of the problem. I found another topic in mql5 that gave as a solution, take mt5 file from 'program files' and put it into C:. Now it works!

I have a dell laptop E4310, initially the computer seems to be in good order. However, for some reason it does strange things that I can not understands. The computer initially, was running windows 7, then I upgrade windows 10, then I installed mt5, that in general works without problem. Then, I tried to install an indicator and when I try to compile I got an error. I also tried to install other indicators from internet that should be working ok and I can not compile them. I tried them with my pc and I managed to installed, so the problem must be on the laptop. I format C and reinstall fresh window 7 expecting that everything will be ok. Unfortunately, still the problem.
I am completely desperate, I don't know what to do. I need mt5 working properly in this laptop.
Any help will be very appreciated.
