Windows 7 Pro 64-bit
2.74, upgraded over top of 2.73 (didn't uninstall first)
User paths are incorrect after install
My working account (dennis) is a limited user, so the blender install prompts for the administrator password to do the installation. With 2.73 there were no repercussions, but with 2.74 the path for temp files, the default "Documents" version, and the default load/save path are all \users\administrator\..etc.. instead of \users\dennis\..etc.. . Temp can be fixed through user preferences, but not the documents path.
