I asked someone else this recently. Did you reboot after the installation/updated?
Steps to reproduce the crash:select itemlocate->on disk (external)inside opened explorer window: activate context menu on any media fileresult:explorer crashContext information:Doesn't happen when shell extension is disabled (done using http://www.nirsoft.net/utils/shexview.html)Doesn't happen inside other explorer windows (only those created by "locate -> on disk")Using MC17 17.0.147 Under WIN7 64 BTW: what is he purpose of that "context menu extension"? Activated or not I do not have noticed any difference on explorer context menus.
