Plugin UnifiedPluginInstallerAgent.exe Issue

When installing DxO Nik Collection 8 it does not appear as the photoshop plugin. DxO have been helpful however the issue seems to be that this file (UnifiedPluginInstallerAgent.exe) should be in the folder (C:\Program Files\Common Files\Adobe\Adobe Desktop Common\RemoteComponents\UPI\UnifiedPluginInstallerAgent) when Photoshop installs and no matter how many times I install photoshop from creative cloud this does not exist. Can anyone help? Thanks
