Ultimate Edition 2.5 64 Bit can be used only by 64 Bit Machine.
Single-button upgrade is one of several special characteristics of this distribution. Other main features include custom desktop and theme with 3D effects, support for a wide range of networking options, including WiFi and Bluetooth, and integration of many extra applications and package repositories.

Ultimate Edition is based on Ubuntu but should not be confused with or be considered Ubuntu. The major difference between the two is that Ultimate Edition has its own repository that contains restricted multimedia drivers as well as packages that require license acceptance to install.
