file manager not complete a double click action

[maxchen]

Lubuntu 14.04.1 + LXpanel 0.7.0

I install virtualbox, then install the extpack of virtualbox. If I use PCmanFM, double click the extpack, it launch Virtualbox, and the extpack is not execute (no popping up the dialog to install it).

I install thunar (XFCE's file manager), double click the extpack, it launch Vitualbox, and pop up the dialog to install extension pack.

Do you have a problem with LXDE or one of its components? To receive assistance from anyone on the forum you must provide us with a clear question, hopefully what you have already tried, and/or the desired result.
