These are binary builds of Device Explorer. It is strongly recommended you use the main build, DevExplorer.exe, for 64bit Windows versions. Many features will not work if you run the 32bit version on a 64bit OS. The 32bit version (DevExplorer-x86.exe) is provided for 32bit Windows only.
This is a portable app requiring no installation and creating no files/settings of it's own (though it invokes OS APIs to manage hardware).
Note: Most functions beyond listing devices and show properties requires running as administrator. When run as admin, the SeLoadDriverPrivilege is enabled in order for some features to work.
Version 1.2 contains internal changes; there's no feature updates vs v1.1
