I like to find where excel stores the toolbar file before I put the transfered
version there.

I'd start excel and then tools|customize
create a new (dummy) toolbar.  Add an icon to it.

Now close excel and then use windows start|search to find that new *.xlb file.

If you find more than one, look the date/times and delete them all (or move them
somewhere else).  But keep track of the folder that held the current *.xlb file.

Then copy that *.xlb from the CD to that location using windows explorer.

Right click on it and choose properties.  Make sure it's not marked ReadOnly.

Then start up excel and see if it worked.

This technique works ok if you're staying with in the same version of excel--but
if you're upgrading, I'd make a note of the icons I liked and rebuild it from
scratch.
