I"m unsure about Poser 3, but Poser 4 dinnae leave anything outside itself... I.E. .. nothing in the system files etc.. everything internal to it's own directories.. so.. in theory deleting the directories should take care of it... but.. as I said.. I'm unfamiliar with P3... it's the request for an administrator account that causes concern. 95B chouldn't give that error.. unless you're connected to a LAN....
