MT4 cannot load EA.ex4 - page 2

New comment
 
Papaprcyde:

So i tried to add an EA to my MT4. I opened my metaeditor and clicked on experts, in the experts folder there were two other folders titled 'advisors' and 'examples'. I copied it to advisors, restarted my MT4 and still cannot access it on my navigator panel. The files are titled ex4. and mq4. but did not pop up despite the other default advisors appearing. I really need help.

Note: Every site i checked for help online does not have a drop down menu with 'advisors' and 'examples' under 'experts', they just have one folder 'experts advisors'.

I'd appreciate any help. Thanks.

You are off-topic. This topic is about an ex4 from the Market, which is available in the navigator.

Your problem is completely different. Check the following :

1. You don't need to restart MT5 to refresh the Navigator. Right-click inside the Navigator window and click Refresh in the popup menu.

2. You problem is most likely that your MT5 is launched with in "portable" mode while your MetaEditor is not. Or the reverse. On both program, use File->Open Data Folder and check the path. If they differ it's a "portable"mode issue.

This is a MT5 comment, but it works exactly the same for MT4.
 
I have similar issue, I have an auto trading application which works on meta trader 4, when I click on download application the wizard comes up but it won't work, it says c;/ programs isn't a valid root directory, anybody have any ideas please, thank you
 

Hi im using an expert and was working fine until yesterday, I run it on a VPS and now it uploads but instead of running I get this error.

The strangest part is older experts work fine but if i recompile them they also stop working any help will be much appreciated.

Yes i had same issue - Can't load MT4 Indicator and this is the solution - indicators downloaded from Market have to be inside the Market folder


I tried to remove them (copy and paste) into main indicators folder. It still worked on that MT4 installation. But when I tried to do it on VPS it said 'Can't load' and only worked when I deleted the indicators from Indicators folder, logged into Market on that MT4 and downloaded the indicators again to Market folder. Weird that the indicators are somehow locked to work like that but later when you remove them from Market folder to Indicators folder they still work.

Because activation is per computer., and your VPS is the other computer (which is different from your home computer).
 
I had thesame issue and I found out it was because my MT4 updated itself so i reverted back to a previous version and it works as expected. 

C:\Users\<YourUserName>\AppData\Roaming\MetaQuotes\WebInstall\mt4clw

If there are any files in this directory, delete them before attempting to launch your MT4 terminal.
The above directory contains the update files so you need to delete them so it won't auto update.

If you need to revert to a previous version of MT4, ensure you have made a backup copy of at least the terminal.exe and metaeditor.exe files from the installation folder. Overwrite these files if you wish to revert back in the C:\Program Files (x86)\<Metatrader 4 Installation>

that is because it is an illegal copy and so will not work after the recent MT4 update...
