So its not High DPI aware.
As it's basically a "bunch of web-pages" (CHM = Compiled HTML), you can use <Ctrl +> and <Ctrl -> to zoom in/out. Or Use <Ctrl> plus the mouse scrollwheel.
The underlying issue is in the CHM itself. It uses px (pixels;absolute size) instead of pt (point;relative size) in the CSS stylesheets (I just decompiled the CHM to see what's going on)
Like:
font-size:13px; instead of
font-size: 13pt;
CHM is more or less abandoned by Microsoft, in favor of a new (much worse) help system. Part of the reason was that because it was HTML, it could contain (silently executed) active code like JavaScript. That's why it gets blocked.
If you would put the unblocked CHM somewhere on your network, it *still* would show you a blank page if the zone in which it is placed (trusted site, Intranet, etc) isn't allowed explicitely or this specific file isn't allowed explicitely.
