Why does WiDi not install on my Dell Latitude E6420 even though it meets the system requirements?


Hello Community,

it seems that I can't get Intel WiDi on my Dell Latitude E6420 to work. According to Dell's system requirement site (http://www.intel.com/content/www/us/en/support/emerging-technologies/000014932.html System Requirements for Intel® Wireless Display (Intel® WiDi) ), my laptop should meet every requirement:

I have an Intel Core i7 second generation processor, Intel HD Graphics 3000 and a Centrino Ultimate-N 6300 network adapter. So it seems that it should install without any problem.

Buuut... Of course it doesn't. I have also tried installing it via the Dell installer for the 6300 network adapter (http://www.dell.com/support/home/en/us/debsdt1/Drivers/DriversDetails?driverId=CP74X Intel 6235/6300 Wireless Display (WiDi) Application Driver Details | Dell US ) but that gives me a compatibility error, too.

Does anyone have an idea what could be causing this, and is there a fix for this problem?

Thanks in advance!

Hello roastbeef112,

Thank you for your post. However, we regret to inform you that http://www.intel.com/content/www/us/en/architecture-and-technology/widi-pro-widi-discontinued-notice.html 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.
