OK...so I bought a 4D systems 4duino. I wanted to get it working with the hello world program.
Ran into the well known linker plugin problem. While trying to solve it I made the really bad decision to delete the Arduino IDE directory.
Now I can't get any version of Arduino IDE to install. They all tell be that I already have 1.8 installed when I can assure it I do not.
How do I clean out whatever is blocking me so I can start over.
Yes, I know it was stupid and incompetent. So will you help me?
