I am switching from my old 32-bit PC to a new 64-bit PC. I am using PortableApps on a USB stick. What do I have to pay attention to so that the existing programmes run on 64-bit?
I have read: Firefox Portable is a dual-mode 32-bit and 64-bit app, ensuring Firefox runs as fast as possible on every PC. Is it true that Firefox starts in the 64-bit version when I use my USB stick on my new 64-bit PC? Are most programs in dual-mode and then start in 64-bit mode?
I certainly need to replace qBittorrent Portable 4.5.2 or KeePassXC Portable 2.7.4, which are 64-bit apps only. Are there many other 64-bit only apps?

Nearly all 32-bit apps run just fine on 64-bit, so those you don't need to worry about. Most of our apps we release the 32-bit version only if they have both as there is minimal performance difference. For apps where there is a performance difference or where drivers are required, we do dual mode apps like Firefox which includes the 32-bit and 64-bit versions in the same portable package with the FirefoxPortable.exe launcher automatically running the correct one for each machine.
There are a handful of 64-bit only apps that you'll now have access to once you upgrade like KeePassXC and qBittorrent that would have normally required you to use the outdated 32-bit builds which we release as 'legacy' packages. And some 64-bit only apps like Lagrange and Zettlr which we've never done a 32-bit package of.
Sometimes, the impossible can become possible, if you're awesome!
Thanks for the answer. This was very helpful and I think, for other users too.
