   Thank you for the information!

   As I mentioned in another reply, so far I think we can use this 
script to temporarily change the 'current installation' if needed for 
some external installer package to correctly recognize where to install 
its content.

   <bike-shedding>If we do use it, I'll most likely modify it to first 
make a backup copy of the original registry key and use that later on to 
restore the original registry state instead of reconstructing its 
content to what the script assumes it should be.</bike-shedding>
