OpenCL Driver installation issues on Ubuntu linux with Intel scripts



 I have been trying to install the OpenCL driver on Ubuntu 16.04 using the scripts on Intel's website and ending up with a few errors. And I'm quite a noob to linux, so it will be nice if someone can help me out on this. My system is an Intel N4200 with 505 HD Graphiics which the script claims support. Here are the errors:

Downloading user mode driver... already exists, skipping download...
