Guys, this has all been covered already... :-)

Here's the basic problem for Vista:

  Tip: "Vista 'Gotchas' You Should Know About"
  http://www.sonsothunder.com/devres/revolution/tips/env007.htm

And the suggested approach has been in emails to the list (which I'm 
going to turn into another tip so I don't have to hunt it down each 
time):

Best would be to create your program with just a "stub" (also 
called "splash") executable (that all it does is launch and open 
another stack file on disk. This way, you can install your stub program 
in the Program Files folder, the rest of the running stack(s) that make 
up your program in the user's Application Data folder, and then save 
any data that the user generates into the user's Documents folder. 

What that translates to on XP and Vista is:

1) Main Executable Stub 
	Install Location:  specialFolderPath(38)
		Windows XP - C:\Program Files
		Windows Vista - C:\Program Files

2) Additional Program Stacks
	Install Location:  specialFolderPath(26)
		Windows XP - C:\Documents and Settings\Ken\Application Data
		Windows Vista - C:\Users\Ken\AppData\Roaming

3) Generated User Documents
	Install Location:  specialFolderPath(5)  [another form is 
specialFolderPath("documents")]
		Windows XP - C:\Documents and Settings\Ken\My Documents
		Windows Vista - C:\Users\Ken\Documents

If you don't already have this page bookmarked, I would suggest it:

Well, there's the rub - there isn't a simple answer. The problem is 
that for truly "locked down" users, the application itself would need 
to elevate its permissions to take actions that the currently logged-in 
user's permissions do not allow. OS X we can do with "sudo" and get 
authorization; Trevor just found a way to ask for authorization under 
Vista, but for other Windows flavors there isn't a solution for 
Revolution that's been made known.

What I've ended up needing to do is to request that Windows users get 
added to the "Power Users" group, which gives them some form of 
elevated access, but doesn't quite make them "Administrators". However 
some companies won't even allow that...

----

So the bottom line is that until we have an "All Users" solution in 
place for all platforms, best is to either install for a single user or 
to get someone with Admin privileges to install for All Users (they may 
have to authenticate or acknowlege a security dialog in Vista if the 
User Account Control is turned on).
