Thank you for your post. However, we regret to inform you that Intel® WiDi has been discontinued since August 15th, 2016. With the WiDi forums having been officially removed last December 15th, 2016.
While you do meet the basic hardware requirements, there is a little more to it than that. In a best effort basis, I can point out the following:
1. Older generation processors needed an older WiDi version to match (see picture).
2. For WiDi to work, you'll also need to make sure that you're using the latest graphics and wireless drivers.
3. If your computer has a dedicated graphics card (besides the built-in Intel® HD Graphics), this would need to be disabled in the device manager.
4. The WiDi download you have provided does not list your computer under "compatible systems". Many of these OEM installers use a white-list to make sure the software is only installed on pre-approved systems. I also searched through the downloads for your laptop model, but was unable to find a WiDi software download.

We hope this information helps.
