Could not launch the compiler

[matrixebiz]

When I click on Compile with any mq4, I get the above error. Any fix for this?

Thanks

Me too

I have the same problem on two different demo's with different brokers.

My virus scan says it has detected a trojan in a file called metalang.exe.

If anyone has a fix that would be great.

What is the name of the compiler? is it just MetaEditor.exe? I have that in my directory.

it's called MetaLang.exe

[matrixebiz]

Yep, that did it. The file was missing ?? Weird

Just copied MetaLang.exe from another folder.

Thanks

I have this issue and it won't stop. It just keeps deleting even though I turn off all my antivirus programs. Any ideas?

It has been reported that some anti spyware programs are deleting metalang.exe (here is one post about it : Sunbelt Software, Counter Spy (AntiVirus Software) -- Keep remove MetaLang.exe causing malfuning of Metaeditor - Reminder for MQL staff - MQL4 forum )
