Hi Installing Parsix 0.90 need to CDROM faster than 40X and buffer more than 96KB. If the speed and buffer less than those,Parsix 0.90 can not install or will be install badly. For example i could not install it with CDROM 40X & 96KB buffer but could install with CDWriter with 52X read speed and 2MB buffer (tested in some computers and some CDROMs). Thanks Yousefi
