oops, Vista Problems and CopyPush

[Joe]

It seems I am wrong...
I need to change the tempory data file
location to the %CommonApplicatonData% location.
It is no longer allowed to write files in Program Files.
In addition I probably need to spawn cpHelp.exe,
for its double duty to update the resource, 
to %wintemp% --- it may not execute from %CommonApplicationData%.
I am not sure of this...

In addition, I would need to write an installer that needs
to be run in Administrator mode, in order to install the
app in Program Files to be available for all users... 
(I would make it a choice, otherwise each user would have
to install the app.) 
Not only that, in Vista, Users/Public/Desktop or
Windows/All Users/Start Menu for installing links can only
be done in Administrator Mode, and I would have to hard code
them after checking for a Vista machine, since I do not know
any API or .Net functions to access these locations.  By the way,
I read that after .Net 3.0 an application cannot ask to be 
upgraded at run time via UAC, and the only way I read in Vista
is to include a manifest in the EXE, or in the same location.
Maybe this is allowed since it is at application start up.

Be that as it may, I do understand the need for security.  But
I had hoped to have a set of 5 games or so to market.  But a 
Verisign security, is very expensive; and asking to have
Administrator Priviledges from the user would probably scare
more people away without one.   But the rate I program, Windows
will be obsolete before hand anyway :-).

Does anyone here have apps available that run on XP and Vista,
and need to have multiple users access the same data?

take care,
