I have a Dell Inspiron N5110 15R.
A couple of specs on the machine:
2nd Gen Intel Core i7
8 GB RAM
OS Windows 8 Pro x64
This laptop came with WiDi and all it's fixin's pre-installed. I upgraded from the Windows 7 Home Premium (x64) that came with it to Windows 7 Ultimate (x64), and used WiDi on a nearly daily basis - I mainly watch Netflix, not cable.
When I was considering upgrading to Windows 8, I researched the functionality of WiDi with Windows 8. I found out that version 3.5 was released in order to make WiDi work with windows 8. After confirming that all my other programs would work, I took the plunge.
I followed the instructions on this page: Enabling Wireless Display (WiDi) on Windows 8 RTM | Intel® Developer Zone
Downloading and installing the x64 versions where applicable, however , when trying to install WiDi 3.5.40.0 , I get:
I know this is not correct, as I have been running Intel WiDi for close to a year with no problem, so my Hardware is not an issue. Also, the only change I made to my system was upgrading from Windows 7 (which is compatible with WiDi) to Windows 8 (which is also compatible with WiDi)
Any ideas? Any help? I've seen others post with the same problem, but no solutions have worked for me.
