Quote - Success at last! My son figured out what was wrong. I had downloaded all the files to a USB memory stick and ran the install from that. My son moved all the files to Drive C and ran Poser install just now, and all the content installed this time.

Thanks for your help and patience Bagginsbill.

Hmmm strange because I am having the same issues and mine is on my c/drive i followed the readme to the T and after many installs and uninstalls still having issues, even to install V4 :(
