Packages just with 32 and 64 bit files

One of the main reasons is to ensure automatic switching for the appropriate architecture, rather than users asking "why doesn't my app work?" when they unknowingly switch architectures on a new machine.

Here's our current comments on how 64-bit software works here: https://portableapps.com/node/24371

As all editions of Firefox, Portable Edition are released as dual 32/64 bit applications, we will not be reverting to releasing only a 32-bit version, nor will we be releasing a 64-bit version only at any time.

Note that the only official release we have available as a 64-bit only application is Google Chrome Portable, and it is a test version prior to releasing a dual 32/64 bit application, at which time the 64-bit only version will be retired.

[EDIT] As you've noted, it is possible to delete the 64-bit files if you prefer, or alternatively use >a href="https://portableapps.com/support/firefox_portable#32and64">this method to run always in 32-bit mode.
