Hello,

that patched main executable has indeed a strange first import descriptor...
Some section names contain "KANXUE" which might point to origins of this
"patch".

The Windows loader probably treats this as invalid descriptor (= ignores any
parts of it).
That "meqon.dll" is also referenced by other imports/dlls which have a valid
import descriptor for it, hence the problem will fix itself at later time.
Wine loader might be too strict here ...

Can you "profile" that executable using "Dependency Walker"
(http://www.dependencywalker.com/) under Windows?
It should show how this entry is handled...

Regards
