This error appears because HCnix installer could not find the file libz.so.1 in lib folder of HCnix. This issue can be resolved by creating the alias of libz.so.x.x file with name of libz.so.1 in lib folder of HCnix.
Use the following command to create alias:
ln -s /hcnix/lib/libz.so.x.x /hcnix/lib/libz.so.1
Above command will create a libz.so.1 file in lib folder of HCnix.
