Hello,

 

I have a big Problem. Yesterday I installed the newest MT4 Update and since then I can not use any new EA.

 

I always create the EA with EA Wizzard and then I copy the EA in the MT4 Expert Folder.

 

But, If I start MT4 then, I can not find the new EA.

 

 

And if I try to compile the EA manually with the Editor, I always get the Error: EX4 Write Error.

 

Could please someone help me?

 

Thank you very much

 

Marc

 

PS: Now I see I have posted my Question in the wrong Area. I wanted to Post in the EA Wizzard Support Forum

 

Sorry 🙁

Hello,

 

have you updated your EA Wizard to the latest version and have you run the autoupdates? 

If not redownload and reinstall EA Wizard from our website – even if you alreayd have teh same version, there were some updates in EA generation scripts.

 

 

Also, the new build 600+ changed folder structure of MetaTrader, now you can locate the proper folder for EAs by going to File ->Open Data Folder and there go to MQL4/Experts.

 

The Error: EX4 Write Error looks like there is some permissions problem in MT4, maybe you should try to reinstall it to another folder.

Thank you very much 🙂

 

The Problem was the new Folder structure. Now it works.
