always choose 'daz studio' to install to. also, with W7 you must have the runtimes outside the Program Files area. Vista and W7 does not like any wtriteback to the Program Files.

there will be no issues with Poser's built in runtime as that is part of the initial install.

but any extra content will need an external runtime, otherwise W7 is likely to shunt your new content off to a hidden temp folder.

scripts etc, must still be installed to the core app.

also, if you use some of thiose handy python scripts by D3D, you might need to get a .dll file off the net and install it to the appropriate folder in the (x86) folder. ( sorry, cannot remember the actual name of the .dll atmo, but W7 64 bit does not have it on install )
