Why are you moving it into a new directory? The directory "cd /usr/share/maskprocessor-0.73" is not where that deb installs it
I move my mp64.bin file all over the place and it works fine each time. I compiled it with the kali native glibc.
If you are seeing that error, are you sure that you are using the file from my deb, and not the binary you can download off the web?
