hi patrick, you dont need ram mate thats memory, its refering to space on the hard drive. check if your hard drive is partitioned(it should be) if it is all your important stuff will be on the c drive and gets full up quick when installing lots of programs,on your d drive you should have plenty space (i'm assuming!) so when installing your printer software change the destination drive to the d drive and it should install ok, hope this helps.
