try creating the folder manually then. the install prog should give some idea of where it is trying to install to, so go there and left clic, pick new, folder, and type in the name of the folder it cant make on it's own. also find the root folder that it's all getting installed into. left click and choose 'properties'. i am at home, not on my work LAN (Local Area Network), but find the root folder, left click, and under properties there is some sorta network setting tab. what does it say? I am sure that there is a setting that limites access. pick the one that sounds like it maked the folder avaliable to anyone, raher than 'read only' of such like.
