As you notice on 64-bit, you have /lib and /lib64. It’s just the dynamic linking in the installer is a bit skewed, now run the command below:

ln -sf /usr/lib64/libgssapi_krb5.so.2.2 /usr/lib/libgssapi_krb5.so

ln -sf /usr/lib64/libkrb5.so.3.3 /usr/lib/libkrb5.so

ln -sf /usr/lib64/libk5crypto.so.3.1 /usr/lib/libk5crypto.so

ln -sf /lib64/libcom_err.so.2 /usr/lib/libcom_err.so

ln -sf /usr/lib64/libexpat.so /usr/lib/libexpat.so

ln -sf /usr/lib64/libm.so /usr/lib/libm.so

ln -sf /usr/lib64/libssl.so /usr/lib/libssl.so
