Sometimes you also get that error if your EA or indicator uses a Microsoft DLL from a different Windows version - both having a 64bit architecture.

Example: I was using the msvcrt.dll (on an old machine) from Win7 system folder and later I compiled my EA on Win10. There were no compilation errors, but the EA stopped execution with this error:

"Cannot call 'memcpy', 'msvcrt.dll' is not loaded."

So in this case I just had to grab the msvcrt.dll from Win10 system folder and the EA worked fine.
