Are you running a network version of excel? Whether or not you are
sometimes impacts where personal.xls is stored.

Go to your excel startup folder (to find out where this is go to tools,
then on the general tab look at startup folder). Find personal.xls.
Copy it. Then put it on the server for the others to grab. Then have
them copy and past that personal.xls over their own personal.xls file
(unless they have their own macros recorded, in which case you would
copy the code instead, if this is this case let me know and I can
detail more instructions).

Hope that helps.
