How big is your virtual machine's drive? Go into windows explorer, left-click on the C: drive, and look at the size of the drive, and look at the pie chart to see if the C: drive is filled up. You said that you downloaded SP3 and then when you ran it, then you said it said "no volume large enough could be found to extract the files." When you run the SP3, it extracts and uncompresses all the files within itself to the drive. If you don't have enough storage space on the drive under windows, then it won't extract. What you could do is burn that SP3 file to a CD, delete the SP3 from where you have it on the mac, empty the trash bin, and otherwise do a clean up in windows to allow for more empty space. And then run the SP3 from the CD and see if that works. Note that this is all different from "memory" ram. People get "memory" mixed up by interchangably mixing up "memory" as either (1) ram memory and (2) harddrive storage space which people particularly newbies may also refer to as "memory."
