Am trying to install WiDI 3.0.13.0 in my laptop Dell Latitude E7240 - Windows 7 Enterprise and according to Intel website its compatible, am using HD Graphics 4400. I made sure I installed all updates from dell.com/support website. Updated my bios and all the drivers including video driver and wifi drivers, then ran widi setup from intel website and after ran widi update tool which installed wifi drivers successfully but keeps failing to install Intel Wireless Display Software Version 5.1.28.0 and this is keep failing. I even tried uninstalling widi, graphic driver and roll backed to original then tried again installing latest driver from dell website and ran widi setup and then update tool again but am getting same error which I attached the screenshot. I also tried installing stand alone that display software version 5.1.28.0 but couldn't install. I also tried installing HD graphics 4400 directly from Intel but its saying its not compatible, need to download OEM from your manufacture website which I already tried and not working. So after this I downloaded Intel Driver Update Utility 2.0 and ran it again but its keep telling me samething. Install the OEM driver from manufacture website.
Basically I tried everything ran windows updates, driver updates, uninstalled/re-installed widi and video card. I don't know what the hell is wrong with this ?? It should work. Any help will be greatly appreciated. Thanks
