The very last suggestion was to download the latest and greatest versions of the sofware.
Go go the download center and download the bits you need.

If you are doing a new domain, keep in mind that your option most likely will be do do it in Windows Server 2016 since Windows 2012 R2 is out of mainsteam support.
The clients from the year 2012 will not work with a Windows 2016-based Active Directory domain. There is also the need to keep software up-to-date becasue of security due-diligence.
Just in case you used this, also remember that our Samba support changed significantly 2 years ago. We went from distributing a "Centrified" version of Samba to only providing an Identity Mapper.
Finally - you don't need the Windows app to distribute software. We provide all the native packages, so if you're using a DevOps solution like Chef, Puppet or Ansible, that would probably be the better way to go.
To install and join:
- Use the native package manager to install (e.g. sudo yum install CentrifyDC) or with DevOps (package CentrifyDC)
- Run the adjoin command (e.g. sudo adjoin -w -c ou=your,ou=container -u your-user domain.name).
