I starting using Disk Warrior just a few months ago.

I have a copy of DW 4.2 on my computer HD (that carries OS X 10.6.7) and one on my external firewire HD (that holds a bootable 10.6.7).

Can I use the DW 4.3 updater to directly update the copy of DW 4.2 I have on my computer HD -- thus not using my 4.2 Disc in the updating process and not burning a new 4.3 disc? Then I'd move the updated copy from my computer HD to my external and delete the old 4.2 copy on the external HD. (I hate using repair discs.)

If so, does it matter where on my computer HD the copy of DW 4.2 is located?
