There is no difference in the end result with either app, but the LAA version of it is written to the "modern" Windows GUI specs, and might be a pinch "prettier" and maybe a bit easier to use??... All that happens is a couple of bits in the header of the executable file are flipped, which lets Windows know that the targeted app is capable of addressing more than 2g of RAM, so whether you are using a 32-bit Windows with 4gig of RAM and also a boot.ini edit, or a 64-bit version of Win10 or whatever, the end result is the same.
