I don't think this is a problem with editions.

I suspect this may be a problem with disk space.

This update is HUGE, on the order of 400+ MB.

The update file is an exe file, but it is just a wrapper around a 400+ MB .MSI file (Microsoft installer file).

So, to install it, you need the 400+ MB for the source file plus 400+MB for the .MSI plus the space to actually install it.

If you attempt to apply this update via Automatic Updates, it tries to put the original copy of the file on C: and puts the .MSI file on C: as well.

If your C: drive is tight on space (probably anything less than 1.5GB is tight in this situation)

What you can do is to download the install from MS, then extract the .MSI file (there is a command line to do this) and run the .MSI from some other drive letter.

Also, you may have to kill the one that Automatic Updates has downloaded. I'm not sure of the exact location of the file, but once you have a copy of it to know the size, you can search for files of similar size on C:
