Progress!! Yes, option two does finally give me the illusive Addon file!! (thanks all)
So back the the zip file. Open the readme.txt and I get
* Copy the files inside the bin folder to your Blender install folder.
* Copy the PyPRP2 folder to your addons directory
Question 1 - what files in what bin folder???
Question 2 - What PyPRP2 folder??
If I unizip the PyPRP folder to a location, all I get is a load of files. There are no directories contained, just the contents of the zip file. What am I supposed to put what where???
Ok, so I create a folder called PyPRP2 and put everything in there and put into my addons directory. I look and I have the Plasma Development Enviroment option listed, but I can't click to enable it.
Anyone care to tell me what I can do with this???
Incidentally, I'm running XP (SP2)
