Unknown Publisher
You may receive a warning of "Do you want to allow the following program from an unknown publisher to make changes to this computer?"
This may be the result of lacking up-to-date root certificates on your installation of Windows, and can be resolved by updating your outdated certificate store. By default, this is done automatically via Windows Update. For further help, consult with your systems administrator and/or Microsoft's documentation, ex. KB2813430.
Unable to launch Hyperview on XP SP2
See Hyperview will not launch on XP Service Pack 2. Note that this should only arise if you did not run the installer on XP SP2 itself, or made shortcuts manually.
