I've just done this myself, the registry key
HKEY_LOCAL_MACHINE\SOFTWARE\SMART Technologies\Gallery\TeamContent\gallery.smarttech.com\ImsManifestXml
points to where the gallery is stored.
I wrote the script below to complement the MSI, it checks for version 10 and updates the gallery location and removes all the unneeded shortcuts!
Hope this helps!
