Error while compiling on Windows

I got the error window below while I wanted to compile to Windows - still yesterday:

This folder is displayed after the screen above:

This one I already saw it before yesterday, but I usually compile for Windows from OS X, so I do not report it earlier (as you can see in the screen shot).

I compiled Object2D, yesterday !

I trashed the four files (image above) and try to compile / I got the same error.
