Describe your issue

When "Ask for administrator privileges once for each batch of operations" within "Admin Privilege Preferences" is set to ON, a stack overflow warning is issues each time a new queue item is started.

Steps to reproduce the issue

1. Settings > Admin Privilege Preferences > Ask for administrator privileges once for each batch of operations > set to ON
2. Start a process (an update n my case). Accept UAC prompt. Wait.
3. A popup; The System detected an overrun of a stack-based buffer in this application. This overrun could potentially allow a malicious user to gain control of this application. NOTE: This occurs AFTER installation begins, not while downloading is taking place.
