I agree. I think there driver/application is broken and there lack of communication is evidence of this. I have an Asus N56VJ with WIDI it's been over a week and there is no response on this forum about why I get, "This platform is not support"
I third this. I have all the latest drivers and appropriate hardware, but can't install the WiDi software. I have no answers, and don't know what to do next... Ugh.
Dell has tried to help me a few times after the initial contact but it has been of no use. the first suggestion was to somehow go back to a previous version of my Nvidia driver so i could enable the integrated graphics but that never worked; there was no option for that no matter what i did. the second suggestion to to enable My Wifi or something to that effect but that was already activated. i haven't heard anything else since.
so, still no solution. Intel doesn't have any info, Dell doesn't have any info. it's one big mystery.
thanks. i used the link you included in your thread/post and it downloaded the installer package but when i tried to execute it, nothing happened. the UAC warning would come up, i'd grant it permission and then...nothing.
i tried multiple times with the same result - nothing would install 
find a working installer for .net framework 3.5 on MSFT website. I used the one from the page i linked. you might be able to do it from the "add features" control panel too (in win8) or windows update optional components on win7.
I tried finding something else and the only thing i could find is a SP1 installer and it didn't do anything either... ugh. This is ridiculous. I'll have to try dell at some point. Any other suggestions? Thanks for your help.
SP1 should work. try this full installer

for me it doesn't matter - neither installation tactic works because my system already came with 3.5 SP1, otherwise shown as 3.5.1
i am so bummed at Intel and Dell for this. at least the Dell technician keeps contacting me with suggestions and stuff but honestly i am not sure why the Dell tech can't inquire within and figure out what is special/different about WiDi-enabled machines vs. those that don't come with that little decal on the palm rest. honestly, this is mind boggling.
that one doesn't work either, g. And built, you are absolutely right. There's no reason that NEITHER of these supposedly accountable companies should not have an upfront answer to this. It doesn't make sense. Ugh.
My guess is they will discontinue WiDi and move on to miracast, that is why they have such terrible support for it. I called intel support...first they told me my machine wasnt compatible, then they told me it was Dell's problem...finally they transferred me to a manager who lied and said the drivers on their site are only for intel motherboards, not for intel chipsets. When I started telling him it was not true, he very quickly said "thank you for calling intel....." the complete speech and hung up.
I wouldnt mind if it was just drivers, problem with WiDi is that it required external hardware which if the drivers dont work, the external hardware (netgear devices or even TV sets) become kind of useless.
I got so frustrated with Asus. I returned my widi receiver and got a Warpia Stream HD and it works. Widi has so many stupid requirements and bad implementation on different manufacturer laptop it's not worth it. Doom on you Intel and Asus.
