This compiled binary is provided for convenience, but where possible, install the Debian package. 

If you must use this binary, first, extract the zip content to a folder, ensuring the "libs" subfolder exists
in the same folder. Then ensure it has executable permission

chmod +x Quickhash-GUI

Then either double click it, or execute it via the terminal : 

./Quickhash-GUI

Note it requires libc.so.6 version `GLIBC_2.34' or above to run, so may not run on older versions of Linux.
