Try rebuilding your desktop
Please note that RAM Charger is probably working even
though you may be unable to open the RAM Charger General
Settings from the control panels folder. As long as the
"extension" shows during startup, a traffic light at the
bottom of the screen, then RAM Charger is working. You may
access the General Settings through the "more" button in the
Get Info window for each application, or using the RAM
Charger Pull-Down menu in the menu bar.
The RAM Charger General Settings document in your control
panels is a "RAM Charger Settings" application document.
When you open the RAM Charger General Settings document the,
application "RAM Charger Settings" in your "preferences"
folder should be "launched".
If this fails to happen, you can go to your startup disk,
and open RAM Charger Settings directly from the preferences
folder in your system folder. You may also open RAM Charger
General Settings from the RAM Charger pull-down menu in your
menu bar. Just doing this may teach the system "where" "RAM
Charger Settings" is, and thus the RAM Charger General
Settings document in your control panels may subsequently
If this fails, you may need to "rebuild you desktop",
which contains a catalog of all the applications on your
computer. Doing this should add an entry in the desktop
catalog so that the system knows to connect the RAM Charger
General Settings document to the "RAM Charger Settings"
application. You should then open the RAM Charger Settings
directly from the preferences folder in your system folder
to be sure the system knows to open that specific copy of
RAM Charger Settings, in case you have multiple RAM Charger
Settings applications stored on your computer.
To rebuild your desktop restart your computer and hold
down the "command (apple)" and "option" keys as the desktop
and menu bar appears (at the end of loading all your
extensions). If you are holding down the "command (apple)"
and "option" keys as the desktop appears, then you will be
asked "Would you like to rebuild the desktop?" - answer yes.
This is documented in your "Help menu" in the Finder under
"Shortcuts" (restarting the computer in Apple Guide).
