Cubase 4 Won`t load

Hi there i am trying to load cubase 4 and it packs in when it s midway loading the plugins, i also have cubase 6.5 and 8.5 on the same computer and they work fine ,i do have trouble installing cubase 4 from the original disc something to do with other processes interfering with the installation and restart and try again but it does actually install to some degree.i am on windows 7 32 bit ? thanks

i downloaded the cubase 4.5.2 update and it worked fine .doh!
