Re: Problem with write-protected app folder on Vista

Do some users have UAC (user access control) turned on and other have it off
when using Vista?
I have been testing my applications under both senerios...
As for the autoupdate answer, I am looking for that answer as well... -
Vista will not allow any "writes" to the Program File area either, (no INI
or config files should reside under the Program Files) so I am looking
forward to how we implement AutoUpdates...
Thanks,
Doug

I am using AutoUpgraderPro from http://www.appcontrols.com; however, you
don't need to be familiar with this component to answer my question. It is
a
component that allows automatic updating of an application from the web,
which I am using it in a commercial app. In general it works very well,
but
recently some users on Vista (but not all) have reported that the upgrade
does not work. The new version is downloaded, but it is unable to
overwrite
the previous version. I have emailed the vendor of this component and this
was his response:
"Unfortunately this is known problem of Vista, when the application's
folder
is write-protected. Vista tries to do virtualization and copies downloaded
files to virtual folder, but they unfortunately cannot be copied back to
application's folder to replace old files. To solve this you can do
either:
manually set write permission to the application's folder, or set write
permission when you create folder by setup program."
I responded to him to ask why the app folder would be write-protected in
some cases but not others but he has not responded (in general he has not
been great about responding to email). So I need to know the reason for
that, and any solutions to this problem.
