Windows Vista and 7 has changed how programs have write access to protected directories without elevated administrative privileges (User Account Control). Programs do not have write access to directories like "C:\Windows" or "C:\Program Files" (or even "C:\Program Files\Quake III Arena", resulting in issues with saving maps to their game install). This is in itself by design (and rightly so) and is not a bug, though it does cause a few complications for Radiant's older file structure.
GtkRadiant 1.4/1.6 stores a number of files in the program directory that requires read/write access but on Windows Vista/7 it is unable to do so. Files like logs, local.pref, shortcuts.ini files, etc.
GtkRadiant 1.5 installs correctly by placing files that need write access in "C:\Users[UserName]\AppData\Roaming\RadiantSettings\1.5.0\".
