HouseBuilder Plugin

There is something amiss with my downloading the Housebuilder Extension. I am using SU 8 and I successfully downloaded HB on my laptop, but can’t get it to show up on my desktop. The HB files are in the Plugins folder, but when I try to install through SU, it is looking for the .rbz file and not the .rb file. I know the z = zipped, but there is not .rbz file in the HB folder. The laptop successfully loaded the .rb file, but the desktop won’t. What am I missing?
