If you use the .exe installer it will ask you which runtime you want to install V4 to, and leave a shortcut to initialize V4 on your desktop. Afterword you can move that icon from your desktop to somewhere else in My Documents (say create a folder Daz Initialization Shortcuts to put future M4, K4, etc in)...

The dust settled, thinking "what a fine home, at least for now" not realizing that doom would soon be coming in the form of a vacuum cleaner.
