Okay, missing something on install

[Culpeper]

Running 'avastgui' from terminal...

(avastgui:8164): Gtk-WARNING **: Unable to locate theme engine in module_path: "qtengine",

I do have gtk-qt-engine installed.  It works okay in super user mode.

please try:
AVAST_FAILSAFE=1 /path/to/avastgui

[Culpeper]

culpeper@linux:~> AVAST_FAILSAFE=1 /path/to/avastgui
bash: /path/to/avastgui: No such file or directory
culpeper@linux:~>

Also, running Avast from the menu icon of course doesn't show any errors.  I just noticed that the interface look a little different so I tried it from the terminal.

AVAST_FAILSAFE=1 /usr/bin/avastgui

is the correct command by default

culpeper@linux:~>  AVAST_FAILSAFE=1 /usr/bin/avastgui

(avastgui:8183): Gtk-WARNING **: Unable to locate theme engine in module_path: "qtengine",

[Dublin]

please, try to install gtk-qt-engine

[Culpeper]

please, try to install gtk-qt-engine

It's installed.  It was installed before the new installation.  It worked fine using the beta program.  It works fine running from root shell.
