Thank you very much for this swift answer but anyway at my age (53) I'm just a novice so it is not that easy. I run Poser 5 and Pboost did not work. I think it's for NT and I use XP...I get error 4 could you explain please:" copying the download folder ( I know where it is)..to the hard drive..(where do you click?) before this I opened separate folders and with Daz they got installed allright... but I think your system is easier..(not english speaking so excuse the language.. Belgium this one) o.k. nice the reactions on this forum, creativity is what man keeps going...
