always choose 'daz studio' to install to. also, with W7 you must have the runtimes outside the Program Files area.

Why? I don't select DS when installing to Poser, I always select my Poser install and the DAZ installer does it no problem.

There is no "must" about having runtimes outside "program files" in Windows 7, it all depends if you have the UAC controlling it or not, if you don't then it works in there just as well as anywhere else.

This is why I asked the OP if he has the UAC on or off..

Injustice will be avenged.
