Software downloads will extract to a new folder named C:\ASD and then install from that folder. The software will install to the C:\program files\ASD folder. It is recommended to leave the installer in the C:\ASD folder in case a software repair is ever required.
RS3 and Indico Pro version 6.0 will use the C:\Documents and Settings\All Users\Application Data\ASD\ as the data folder for Windows XP or C:\Program Data\ASD\ for Vista and Windows 7.
