I would just like to post how I was able to successfully get my Delta1010lt to run under windows 10.
I almost gave up after relentlessly searching the internet and pulling my hair out.

I attempted to normally install card after a PC and OS upgrade. I bought my MoBo with a PCI slot specifically for this card. No luck, all I was getting is the blank mixer panel and no device in manager. I was about to put it up for auction and get a USB interface. I gave it one more shot but paid attention to the flow of actions.

-Fresh Win10 install.
-Installed all MoBo and OS drivers and essentials.
-Restarted one final time after all installs.
-Once logged in, shut down.
-Installed Delta101lt card in PC and connected break outs.
-Started PC and Downloaded the cards install from M-Audio and unzipped to my desktop.
-Right clicked on the install once downloaded and set compatibility settings to:
Run for Win7 with Run this as Admin
-Apply
-Ok
-Double clicked installer, finished install.
-Restarted
-Opened the Delta101lt mixer and WoooHooo!!

I have been up and running for 3 days now.

Hope this helps someone in need!
