Vista, virtualization, and hairlessness

[Richard Gaskin]

I've been pulling my hair out over this, and even after searching the 
list archives (many of which have mysteriously become less-convenient 
gzip files :\) I still can't turn up the final word on how to solve this:

I have an app in which we allow customers to register it once so it can 
be used on any client machine which has that volume mounted, such as a 
school computer lab.

On OS X and XP, simply writing the reg data into the application folder 
works great, provided of course the person doing the registration has 
admin privileges, which for these scenarios is common.  So far so good.

But on Vista, the same program using the same code thinks its writing to 
the program directory during registration, but it turns out that it 
isn't, and subsequent users report that the program isn't registered.

I understand the basic concept of Vista's virtualization, but here's 
what I don't understand:

Where do I write my reg file so all users can access it?
