Currently the linux AV agent requires us to install 32-bit libc6, libstc++6 & host of other 32 bit packges. Installing 32bit packages alongside 64bit packages works fine on modern Linux OS versions but not on earlier versions. On Ubuntu version 12.04, 14.04 , you can't put 32bit libc6 on 64-bit systems that already have libc6:amd64 installed. System complains about conflicts.
Request the development team to have support for 64bit libraries for the Linux client instead of 32-bit binaries.
