MetaEditor: EX4 write error

Hello traders,

Last week I've installed Windows 10 (64 bit) on my trading computer. Since that moment I get an error when I compile a script, indicator or an EA. The error description is "EX4 write error". This has something to do with Windows 10, because I'm getting this error on all my MT4 platforms (FXCM and Citibank).

I hope someone could help me.

Thanks in advance,

Ok then check to make sure you have write permissions on the file and directory

Could you please tell me where I should change the write permissions?
I've already edited the folder permission and the permissions of the metaeditor and terminal.
I'm not getting the error anymore, but when I compile an EA it compiles fine. But when I backtest the EA the settings weren't changed..

It's really strange..

Thanks

I had that problem yesterday, when updated Win10 and Metatrader 4 920
The solution was to restore previous version of metaeditor. 5.0.0.934
/portable is working too.

Metatrader has been like this for a long time, if you have an EA loaded in the tester and do some changes in the editor then compile it the inputs do not update in the EA loaded in the tester, you have to open Expert Properties and click reset before those changes update.
