Quote - P7Pro users need to install M4 as a DAZ Studio app rather than a Poser app according to DAZ installation instructions. There's no explanation as to why this unintuitive approach was taken.

It looks like Adam Thwaites put up the first M4 freebie.

The Poser Installation looks for the Poser.exe File.

PoserPro has PoserPro.exe and that GD Installer doesn't recognize it.

I made and external Runtime and used the Daz Studio choice.
Everything installed just fine, apparently DS Installer doesn't give a dam where things go.

I then went back and deleted all the DS files.

Poser7 SR3 and PoserPro will run both V4 and M4 just fine as and external RT with No !Daz Folder in the Main RT Libraries.
