Do what Neil said, but this is a special case because there is already a 
property specifically for this called ARPINSTALLLOCATION. If you use this name, 
it's possible to get it back from MSI APIs using MsiGetProductInfo().

You would need to author your install to remember it, see this post

Hi

I need some confirmation on what I should do about setting the installation 
folder during maintenance mode.



When the first time install sets the install location to non default location, 
does the msi remember this for subsequent maintenance operations?
Or should I create a custom action during maintenance mode to read the install 
location from the registry and re-set it?  I am finding different results with 
my testing. Sometimes this install location is remembered during maintenance 
and sometimes it goes back to default.



Thanks!

Uma
