SM Agent 9.2.3 installation prompting for Bitness 64bit or 32bit

Need some clarity on which bitness to select while installing SM Agent on Enterprise & Deployment Server.

As per Install Guide of 9.2 following are the notes:

Notes:

These considerations apply to bitness:

■Each Server Manager Agent can manage only a single bitness of target objects. That is, it cannot manage multiple objects if the objects are a mixture of 32-bit and 64-bit bitness.

■If the target being managed is an Enterprise Server or Deployment Server, select the bitness of the EnterpriseOne server.

■If the target is not an EnterpriseOne server, you can select either 64-bit or 32-bit.

■If more than one target is to be managed and the targets are of different bitnesses, you must install a Server Manager Agent for each bitness.
