Making programmes available for all users

[always_been]

I have discovered that many of the programmes I have downloaded since
installing Vista are not available to other user accounts on the computer.
For example, as the administrator I run windows live messenger, but if I log
on as a guest, the programme cannot be found.

Can anyone help me figure out how to make all the installed applications
available to all users? Thanks
