[tex-live] Windows XP X64 uninstall goes badly...

Follow up report to this issue.

(For the record: during all of this I am logged in as admin,
and I am installing into the default area c:\texlive\2009)

Original install was done from DVD.
The next time I tried installing from a copy of the
install disk in hard drive to help speed things up.
(Otherwise it take almost 2 hours to install in this system.)
On second install, everything went smoothly as before,
except this time, TeXLive was not inserted into the path.
On uninstall, everything was properly removed, except
for all of the executables like last time.
I have no idea why that should be happening.
I am logged in as administrator and can easily delete
all of the leftover files manually after the uninstall.
On the thought that perhaps some other process was
perhaps interfering with the install and uninstall,
I rebooted the machine and stripped it down,
turning off literally everything non-essential.
Unplugged it from the internet, turned off
COMODO software firewall, and removed all
running process associated with the virus checker.
Then installed, rebooted, uninstalled.
As before, no PATH on install, and
all executables left over after uninstall.
I did the same thing with another machine that
I have running XP Professional (32 bit) and
on that machine everything installed and
uninstalled perfectly.  I compared the file
attributes on both machines and there is
no difference.
Any idea why Windows XP X64 would do something
this strange?  It's not as if I have any problems
on install or uninstall for any other software
I have...
Man all of this installing and uninstalling testing has
cost me an entire night.  If there is any more information
I could provide to help tracing this problem,
please let me know.
I also have a machine running Windows 7, 64-bit version.
I wonder what would happen on that machine.
Perhaps I can test it tomorrow.

The only problem that comes to my mind is file permissions.  Was
installation for all users (admin)?  Did you install under
%ProgramFiles%?  TL version (NET or DVD)?

I don't recall a report of this sort.

The uninstallation process goes like this:
- remove shortcuts, file assocs, etc., for each installed package
- remove TL from the search PATH
- unregister uninstaller
- delete TL directories

Since most of TL files are gone in your case, the installer won't work
any more and you probably have to do the remaining steps manually.
