Receiver is the framework in which plugins (Online, Offline (streamed), SSO (password manager) etc.) were managed by. As users frequently just installed the Online Plugin it was confusing that the client needed for other operating systems was called Receiver.
Citrix decided to just go ahead and force users to use Receiver for Windows and make the Online Plugin a default addition thus making the naming consistent across the board.
This was ok on the whole, but since version 3.3 they have made a prompt which asks users for the URL for Citrix Storefront. This does not accept a PNA web address and can be throughly confusing to users who are using a standard Web Interface to launch their applications!
The string provided in my earlier blog post still works to remove the receiver branding and popup, but it is not like end-users will install the software like this on their own PCs.
If you still want to use PNA you need to download a different version of receiver (receiver 3.3 Legacy PNA). This can be found at the following website (MyCitrix login required)
If you do a basic install, it will not provide the old blue bubble in the system tray and will only show applications in the start menu. To make it install like it did from the good old days use the installation string as follows
CitrixReceiverEnterprise.exe /silent ADDLOCAL="ICA_Client,SSON,USB,DesktopViewer,Flash,PN_Agent,Vd3d" ENABLE_SSON="Yes"
