I have run J installed in Vista "Program Files". I didn't have any
problems running J, doing JAL updates or editing J system files. All
users (administrator or standard) were able to run JAL and install
addons. 

The only thing I found that needs a heads up or warning is that unless
the J session is invoked with elevated permissions (that goes for both
administrators or standard users) (shift right click 'Run as
administrator') any addons will actually be installed to
"c:\users\<user>\AppData\Local\VirtualStore\Program Files\j602\addons".


Same goes if a user opens say "c:\program
files\j602\system\extras\utils\pacman.ijs" in J, edits it to work with
spaces in the path and then saves the changes.  Unless J has been run
with elevated permissions, the file will actually be written to the
user's VirtualStore.

In my experience so far this behaviour transparent to the user as any
call to a file under "c:\program files\" is supplied with the same file
from "c:\users\<user>\AppData\Local\VirtualStore\Program Files\" if it
exists.

>From admittedly limited experience with the scenario so far, as long as
the administrator of the machine is  aware of this Vista behaviour, then
it actually has some benefits. For example it prevents one user from
stuffing up everyone else's J while still giving users the power to
fiddle/experiment.

If an administrator wants to make an addon or edit available to all
users on the machine they can run JAL, then move the desired files from
their VirtualStore to 'c:\program files\' using Windows Explorer. Of
course it would be even simpler if JAL could prompt the user to elevate
permissions so an Administrator could install addons directly to
'c:\program files'

I would suggest that this is something to warn users about rather than
discourage them from.

Caveat: My ramblings above are entirely from my own limited experience
with Vista. I haven't studied the documentation or researched this, so I
may be missing some (important) intricacies.
