I made a password protected PDF file from my 64-bit LibreOffice v6.2.4.2’s Writer in my decade old, updated 64-bit W7 HPE SP1 PC. I tried this PDF Password Remover, in both of my updated 64-bit W7 HPE SP1 & Mac OS X El Capitan v10.11.6 VMs. However, it kept asking me for password to read my passworded PDF file. Why? I thought it was supposed to remove them without asking for it! I was not impressed. :(
