ComfyUI requires an NVIDIA GPU on Windows. No NVIDIA GPU was detected.

My graphics card is RTX3060, which has been working very well, but after installing comfyui 0.3.18, this message appears, unable to proceed to the next step, and my driver is also the latest version.

Do you happen to have multiple GPUs?

The only one

There are a few things that could be wrong. You will be able to skip this screen soon.

If you don’t want to wait, there are some troubleshooting steps you can follow.

1. Check your PATH

Click to expand

In PowerShell, if you run this:

$env:PATH.split(';')

You should get output similar to:

PS C:\> $env:PATH.split(';')
C:\WINDOWS\system32
C:\WINDOWS
C:\WINDOWS\System32\Wbem
C:\WINDOWS\System32\WindowsPowerShell\v1.0\
[ ... many more ]

If you’re missing any of these, something has altered your environment. The possible reasons why are well outside the scope of this.

Windows configures these paths in the System environment variable named Path. If you installed Windows somewhere other than C:\Windows, change the paths.

# Windows install path
$env:SystemRoot

Changes to Path are not automatically applied. The simplest way to ensure the changes apply is to log out of Windows and back in again.

2. Check CIM data

Click to expand 
powershell.exe -c "`$n = '*NVIDIA*'; Get-CimInstance win32_videocontroller | ? { `$_.Name -like `$n -or `$_.VideoProcessor -like `$n -or `$_.AdapterCompatibility -like `$n }"
Explanation

This command just reads data that Windows stores about your hardware and configuration (what WMI reads), and finds NVIDIA matches. It is a new check added in 0.3.23 to resolve issues caused by missing wmic.exe and NVIDIA executables.

Example output

Caption                      : NVIDIA GeForce etc etc
Description                  : NVIDIA GeForce etc etc
InstallDate                  :
Name                         : NVIDIA GeForce etc etc
Status                       : OK
[ ... many more lines ]

No need to upload it - just need to check if it displays something similar to the above, and that the something is not an error (errors are red - red is bad).

If you do not get any output, then an NVIDIA card is not being reported by Windows. Please let us know.
