I don’t recognise that error at all, I looked it up on the web, but I can’t get any ideas as to what it is trying to tell you. It may be a corrupted download, and you may need to clear your browser cache and redownload it. Does this error come up when you run the A3 installer on it’s own?
I also need help with my other content. the stuff for Michael 3.0 will not show up either although it says it installed correctly.
Where are you looking for the installed M3? M3 is in Poser format, and you will need to go to the Content Library tab, then Poser Formats > My Library > Figures > DAZ People to find it. M3 will NOT appear in the Smart Content tab. All figures before Genesis were in Poser Format.
