intel npu driver update error Exit code: 8.

DSCP02

I was going to update the latest NPU driver.
However, I was unable to update it.
Because I exported the following error code.

'Exit code: 8.'

I looked at the error log and it says that my computer doesn't have a driver.

but I already have an NPU driver installed on my computer, but I don't think that update file recognizes it.

I'm not sure what to do here.
I need help.

I got the same issue on my PC. I did a restart and that didn't help.

Also, for what it's worth - I gave the logfile to ChatGPT and it suggested that the installation folder/contents was empty, as the reason.

  1. What is the model of your processor?
  2. What is the brand and model of your system?
  3. What are the troubleshooting steps that you tried so far?
  4. For me to review the hardware and the driver installed, please help generate the SSU logs of your system. Kindly refer to the link below for the steps:

Many thanks.

 

I have a Core Ultra 245K processor, with an ASRock Z890 Pro-A Wifi motherboard. Unfortunately  I'm not invested enough to download a utility to get system logs for you.

 

I've tried running the driver update as Admin, but that's it.
