As time of MT4 change is coming closer, I recommend every one to download the latest versions offline chart indicator.
Do not forget to force the "portable mode", as the current latest versions can only work with the terminal set to portable mode (until fixed in a new version). Look into the online guide or read other user's notes and recommendations.
The new version is using MQL4 folder rather than experts, so wherever the installation guide refers to experts/indicators, in the oncoming version it should be translated as MQL4/indicators.
See the quick fix description in the user guide.
