Zip package, 38.2 MB, with DAEMON Tools Pro version 8.1.0.0654 bundled together with a crack, according to the name. DAEMON Tools mounts ISO and other disc images as virtual drives and can create images, which helps when installing software or drivers from image files during service work. Cracked bundles are unlicensed and commonly carry malware or get flagged by antivirus, so a legitimately licensed copy or a free mounting tool is the safer choice on a bench machine.
