error while loading shared libraries: libatk-bridge-2.0.so.0

[dosforever]

This is the first I run under Linux.
I unpack the archive iron-linux-64.tar.gz
then

cd iron-linux-64
./chrome
./chrome: error while loading shared libraries: libatk-bridge-2.0.so.0: cannot open shared object file: No such file or directory

OS: CentOS 6.10
SRWare Iron: 81.0.4200.0 Stable for Linux

Please tell me how to resolve the problem, thank you.
