ok i know this is going to sound stupid lol i have tried your first method and got it to work it gives me a list of packages 1.bit vector 2.bit vector minimal 3 bit vector minimal 4 math vector sort index 5 math vector real i have installed all of them but you said 'PPM> install <search Results Number indicating your vectorSpace.pm>' which got me confused so i tried your 2nd method, i have checked the folder and there is no *.ppd file just the vectorspace.pm file? and once this is installed how do i go about executing it? sorry to be a pain many thanx ABz
