Just to make sure: Do you have the PlugIn "Xcompound.dll" needed for 3DSMax installed? You can find out about installed XnView plugins by using menu "Info->PlugIns Information" in XnView.
If this plugin isn't listed, the plugin is not installed (properly). You can download the plugins on the normal download page on XnView Download page. All XnView plugins have to be located in <XnView install dir>\PlugIns
So why don't you expand the support to other compound files like MS (word, excel..).. etc and not just the preview image .. but any image inside it.. (best one for it is edoc.exe .. very powerful.. with it i noticed the PictureIT and Image Composer files..
