User is a member of the Users+ group via DLU -- not an admin so
elevation is required.

Stock (not repackaged) MSI for JRE 6 Update 30 referenced by UNC:

prompt for credentials (as expected)

-launching the MSI via an MSI bundle configured to "run as logged in
user" produces no UAC prompt

Just want to understand this.
