So this has happened to me recently ... I cannot open a folder in Win10 using the Explorer if there is a .ex4 or .ex5 file in it. Change the extension and all is fine. I can still access the files via metaeditor if needed and compile ok, but to attempt to copy etc, no dice.
Yes, I've updated Windows, ran Malwarebytes, ran antivirus, ran boot level antivirus, cleaned registry, defragged, scrubbed all useless files, cleared the Explorer history, re-installed MT4 plus half a dozen other "obvious" things as recommended online. It's the weirdest thing.
If someone has seen this and been through it before your help would be greatly appreciated.
This worked for me I removed Metaviewer64.dll from system32 and boom. No other errors
This worked for me too.
Very Thanks! You saved my life! :D
