Although it
says 256Mb RAM is the minimum requirement, I suspect that in practice you'll need more memory than that for any sort of reasonable performance. I'd also agree with Jolt - the more free space you have on your C drive, the better your whole system will perform. You don't say what the total size of your C drive is, but generally speaking if you have less than 10%-20% free, your system performance will suffer.
