That's not entirely true. It downloads the update and asks to install it, and ultimately the update installation will fail due to a lack of permissions. Experienced with Firefox 2.0.0.2 at university.

I have "update" options disabled if I don't have permissions to the destination directory. Maybe it only affects the possibility to change settings and not the actual update.

If you originally install your app as admin, then you'll have to make the update as admin.
If you install it as a regular user, then set write permissions for the current user for your files. Then it is possible for the same user to update the app.

On Vista you can elevate you app's rights to a more privileged user ( by asking the current user a user name and pwd ). You'll just have to add a few extra entries in the app manifest and some lines of code.
