Plugin Issue - UnifiedPluginInstallerAgent

When installing any plug-ins they do not work and are greyed out in photoshop. DxO (one plug in supplier) 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
