The source code is also on GitHub (visit the Github page for the project via the menu at the top). See the hashes below and check on your own system once downloaded. So you can only use the 64-bit version on 64-bit Windows operating systems.
Note: The the 64-bit version is architecture dependant. It includes change log, readme, user manual, and both executables ready to use. This is the 32 and 64 bit version of QuickHash-GUI for Windows. A newer version of QuickHash is available
