I'm using a Dell Laptop: XPS15 L521X on Windows 8.1 64bit
I was running a program to detect out of date drivers to find which one i needed for this and it stated i needed driver version 9.3.0.1030. Which this one I've downloaded isn't. This one is 9.4.0.1027. It mentions it's for Desktops only but i read on another post that it's meant to be compatible anyway.
The Fail itself is when the install is run it states an Error of: "File Copying Was Not Successful. Setup Will Exit." The file it's trying to copy over is CSVer.dll.
Currently instead i have a generic one due to a Windows 10 upgrade that failed and i had to force windows 8.1 back onto my system. This is my current driver for it: 6.3.9600.19026 from 2006
Just had a quick look on dell and they have a similar driver but with a single digit less version: 9.4.0.1026 (Weirdly is 1017 When file is saved). Ran it and the process was the same but with the exact same result. Fail! Rather frustrating.
I install it as Administrator (So nip that basic in the bud).
On another post it discusses possibly having the registry key showing the wrong thing and to check the Infinst inside the registry. For me, apart from having the Infinst folder all i have is: (Default) - REG_SZ - (Value Not Set)
Now i'm pretty sure it's meant to show a fair bit more than that. It's meant to show the driver version for one.
hmm... my USB3.0 eXtensible Host Controller - 100 (Microsoft), says the driver 6.3.9600.19026 is from 2018. Which doesn't make sense.
