Installing HALion VSTs in Cubase Elements


I recently got the Guitar Harmonics and Alto Glockenspiel free VSTs from the Steinberg website. I installed the Steinberg Download Assistant and activated both products in the Steinberg e-Licenser. The downloader simply gave me two .vstsound files in my downloads folder. After a bit of researching, I found that VSTs should be installed under C:\Program Files\Steinberg\Vstplugins, so I moved the files to that location. Now I’ve navigated to the Plug-in Manager in Cubase, and they are not showing up. What have I done wrong?
