Just wanted to submit a bug report.
I downloaded the current drivers for my 944 all in one, I am installing it on WinXP x64 Pro.

When I run the setup program, and click on local installation, it responds I do not have enough free disk space.
I have two 200GB drives, both with about 100GB free, so this is not the problem. I believe the problem is that my drive letters are not the normal C: and D:. My primary hard disk is G: and the second is I:.
It seems the installer is hard coded to either place it's temporary files on C:, or at least check C:'s disk space.
On my computer, C: is assigned to a SD (secure digital) slot, which had nothing in it at the time. If I place in a SD card (from my camera) into that slot, then the installer works fine, and installs all the drivers to G:.

This is some poor programming on Dell's part, the installer should be checking the system drive for free disk space, or better yet asking the user where to install, rather then just assuming it will use C: for it's temp files.

I have sumbitted this to support as well, just wanted to post a heads up to anyone else with this problem
