Install for All Users?

Excellent. TVM!

I used this option:
> you can use the same toolbar folder for all accounts
> It is the good idea to switch toolbar folder to other folder, where all accounts can access it.


I spell out here the steps.
I hope that this may be useful for others.


Copy the folder
C:\Documents and Settings\<user>\Application Data\Microsoft\Internet Explorer\Quick Launch
to C:\

Rename the new C:\Quick Launch folder to perhaps C:\TLB

If True Launch Bar is running:
Right-click the TaskBar,
click Toolbars,
click True Launch Bar to uncheck it and close True Launch Bar.

=======
In the spot where you wish True Launch Bar to appear:
Right-click the TaskBar,
click Toolbars,
hold down Shift,
click True Launch Bar

In the Dialog, choose the new folder, perhaps C:\TLB, [OK]

I needed to adjust the width of the TaskBar, and, because I have True Launch Bar at the top, drag down the divider.

After right-click TaskBar, Toolbars, you now see a new entry,
named after the folder you chose.
=======

Everybody warns you that editing the Registry can mess up the PC.
So it can, but you have to be very clumsy to do that.
If you wish and if your Windows allows it,
you can create a System Restore point so that
if you do go wrong, you can easily go back.

Open a Registry Editor.
One way: Start|Run|type: regedit|[OK]
Navigate to
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Streams\Desktop
Through the menu (varies with the Editor used)
Export the Key to a folder you choose,
choosing a suitable filename - I used TLB.

Close the Editor and everything else and log off.

Log on as another user.
In Windows Explorer or similar, navigate to the folder you chose, find the .reg file that was Exported,
double-click it, or right-click, Open.
In the Dialog, choose [Yes].
Repeat the steps between the ======= lines above.
If necessary, repeat this for other users.
