sudo isn't needed. The second error message is about ./data/ags64: running it isn't allowed, because it isn't marked as executable. To make the zip work, you need to add the execute permission to not one, but two files:
chmod +x ./DUST ./data/ags64
Dev, if you distribute executables for Linux, please use a format that supports permissions out of the box, such as tar (usually as tar.gz).
