When trying to install the hybrid version of the Netvault client on Linux 64bit there will be 32bit libraries needed by linux to install the 32/64bit application on a 64bit os.
Missing library files
If you start running to missing file errors then simpily install the missing packages for the OS accordingly.
Example Error: /lib/ld-linux.so.2 bad elf interpreter
Use Commands-- yum install (missing file/package) Example: yum install ld-linux.so.2
or if you have downloaded the packages seperately then use -- rpm -i /dir/of/package/downloaded/(package name)
