Can't re-install

I installed 1.8 and had some problems. After several attempts, I manually DEL the files from ProgFiles/Arduino.

Now when I try to install, it finds some debris of the prior install and the install just quits. Any clue how to clean up the prior install so I can start over?

thanks

Clean up instructions for windows based computer attached for your pleasure.

CLEAN UP BEFORE INSTALLING ANOTHER COPY OF THE IDE OR ARDUINO CREATE.pdf (347 KB)

Also, for future reference:

Additional Arduino files including driver, cache, temp and libraries are stored under this directory in Windows:

C:\Users\User\AppData\Local\Arduino15

These folders can be removed only if you plan to start completely from scratch with Arduino IDE, libraries and drivers.
