Put a dummy Poser.exe in your PoserPro root folder. That's seems to fool the installer ;o). Just make an empty text file and name it Poser.exe. Apparently Daz didn't think everything through when they made their installers - like different versions of Poser ;o).

So, in essence - what you're experiencing isn't a Windows problem but a Daz problem...lol.
