Where to download... ?

Where can I download Microsoft Mouse Application Installer for my
Wireless IntelliMouse Explorer 2.0 ?
I already downloaded Microsoft Mouse62.dmg which is a new driver, but
it doesn't have fix the probleme.
I make the install (and uninstall) several time with same result.
Each time I try to customize the mouse I got this message [img]http://
