Spectrasonics Plugins Installation

[GuyBrett]

Hi !
I'm trying to install Stylus RMX, Omnisphere and Trillian on my Receptor 2+ Pro.
I may be dense but the information on Plugorama confuses me. Apparently, I don't need the "prep" installer if I already have the Spectrasonics directory in the "Unsupported Plugins" directory. Although this is unclear, I assume this refers to the following path: "Receptor HD/Program Files/VST Plugins/Unsupported Plugins" ?
I happen to have a Spectrasonics directory in that Unsupported Plugins folder. However, when I dig into the Spectrasonics Folder, I can see only Stylus (as opposed to Stylus RMX), Atmosphere (as opposed to Omnisphere) and Trilogy (as opposed to Trillian).
I tried to install Stylus RMX with the "prep" installer and it failed to install.
Then I tried without the prep installer: The StylusRMX.dll file went into the Stylus folder and the Audio2.dat file went onto the Samples/Spectrasonics/Stylus/Stylus Data folder. The Muse Remote Control showed one file to install, I clicked on install and nothing happened ...
Any help would be much appreciated.

Thanks,

Guy
