Thanks for flagging this. Were you able to bypass the warnings?

It appears that systeminformation is unable to operate on your system at all, which is unusual. This likely means WMI or PowerShell is not operating correctly, or being blocked somewhere.

Can you please try running the following PowerShell command (as a non-administrator), and let us know if there are any issues?

Get-WmiObject Win32_logicaldisk

Please post the output here if you're still having problems.

All looks fine. Does this (exact) process work for you? Just testing PATH here.

Whilst holding the Windows key, press R
In the Run dialog box, type cmd, then press Enter
Type powershell.exe, then press Enter
Type $PSVersionTable, then press Enter

If this works, and your AV / system policies are definitely not blocking PowerShell from being used by ComfyUI, let us know and we'll look at next steps.

p.s. You can do inline with `single backticks`, and

```
Code blocks with triple-backticks.
```

'powershell.exe' is not recognized as an internal or external command,
operable program or batch file.

Should be an easy fix - PowerShell cannot be found in your PATH environment variable. You need to include the following directory:

%SYSTEMROOT%\System32\WindowsPowerShell\v1.0

You can access env vars from the start menu, these days:

Edit: Windows comes configured this way; something must have removed the path.

I get the same error with no way to bypass the disk space problem on windows 11 24H2 and here is what powershell 5.1 installed returns:

(get-command powershell).definition
C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe

I am running latest version 0.4.72 and here is the screen shot:

There is 1TB of free disk space. I tried other disks with the same error.

Get-WmiObject Win32_logicaldisk

I have powershell 7.5.3 installed also. I don't know if that is a factor so I uninstalled it and tried comfyui but I got the same error.
