I cannot install flash builder 4.6. Installation hangs while unpacking files

Question

Below is the information from the event viewer.  I am using Windows XP SP3.  I don't know, but I wonder if it has something to do with our roaming profiles.  The place it seems to be trying to unpack to is \\EssexHQVM\Desktops$\user.name\Desktop\Adobe Flash Builder 4.6 Installer, which has a special character in it.  I can't find any way to have the file unpack to another location, it doesn't prompt for a location.

Answer 1

So, the best solution that I have come up with, which is a poor solution, is to run the .exe file on a machine that is not connected to our network and wait for the files to unpack.  Then copy the files to a thumb drive and move them to the computer that I work from.  I can then install Flash builder with no problem. 
This is a kludgy work around that ought not be.  How hard is it to have the unpacking routine prompt for a location?  That would allow me to give it a location to unpack that would not cause a hang up.  Or, failing that, why not unpack in the same location as the file that is doing the unpacking?  Then I could simply place the file in a good location and let it run.
