Application level class paths AS2 vs AS3

Question

Hi,
I've been messing around with my preferences trying to make some external classes available to any new FLA I make. At first I couldn't get it working, but then I realized I was using the wrong location. I was setting the path for my Actionscript class libraries under "Library path:" instead "Source path:".
Now that I've messed around in PREFERENCES > ACTIONSCRIPT > ACTIONSCRIPT 3.0 SETTINGS, I wondered if there's a default that should be listed before my external classes the same way AS was setup?
Normally my AS2 setttings looked like this..
$(LocalData)/Classes
/path/to/my/library
I have those in there for my AS3 'source path' settings, but I was just following the old AS2 info is that wrong?
Thanks,
Dave

Adobe didn't change the registry organization, Windows did.
I write the installers for my company, too, so I am pretty familiar with this.
On 64 bit Windows, the registry path you see when you get the keys in HKEY_LOCAL_MACHINE/SOFTWARE/ADOBE are the 64 bit values if you're calling the registy API from a 64 bit process. They are the 32 bit values if you're calling the registry API from a 32 bit process.
So, you can either write seperate 32 and 64 bit installers, or you can become intimately familiar with the registry redirection that takes place on 64 bit windows. ( None of this is a concern on 32 bit-only installations of Windows )

This is a very important page for installer writers to read:
