I have an application deployed on our intranet, and am having problems with some (but not all) of my users in a remote office (Germany)-

When the users log into their machines in the morning, they click on the link in their start menu to run the application/check for updates.

They get the usual security prompt as if there was a new version (Permission Elevation).
The application downloads, and they are able to run it.

The problem is, they must do this every day (once, when they log in--if they close the app, and run it again from start menu, no 'install), and the version # of the application hasn't changed since the last time they used it.


I'm stumped, because if it were a Permission Elevation issue, the app wouldn't run at all (it's quite invasive, writing to files and to the registry).

I'm thinking maybe the IT department at that office has some strange settings on their profiles?

When this occurs it is the same user on the same machine as the day before.
I don't have a published certificate.
The application is strong named.
I require the latest version, to skip the additional prompt.
This happens to some but not all users.
I have selected "this application is available offline as well (launchable from the Start Menu)"
I use VS2005 to publish, and don't alter the manifests manually or with any other tool.

Any help would be greatly appreciated. Let me know if I didn't provide enough detail.
