When I try to config my xbox 360 wireless controller xinput is greyed out. I recently did a clean re-install of windows 10, and before I did that I was able to customize my controller settings and have xinput enabled just fine.
I've tried using Alternate Setup E since it shows the xinput box checkmarked (although still greyed out) but it doesn't save my custom settings. Before the re-install I was able to use Default Setup D just fine.
I'm using the US config tool just as I did before, and I tried deleting the xinputdll.dll file in both the US and EU config tools and running a file check, and that didn't help either.
I've tried googling this problem but have had no luck with a solution, so any help would be appreciated. Thanks.
