error NU1100: Unable to resolve 'docx <>=0.0.0>' for 'net7.0/any'

When I try to install docfx, I receive the following error;

C:\Users\bburke\AppData\Local\Temp\abc16568-115b-4fc1-b934-c626c9ca0002\restore.csproj : error NU1100: Unable to resolv

ckage source.
The tool package could not be restored.
Tool 'docfx' failed to install. This failure may have been caused by:

• You are attempting to install a preview release and did not use the --version option to specify the version.
• A package by this name was found, but it was not a .NET tool.
• The required NuGet feed cannot be accessed, perhaps because of an Internet connection problem.
• You mistyped the name of the tool.

To Reproduce

1. On a command line, enter dotnet tool install -g docfx

Expected behavior

Context (please complete the following information):

• OS: Windows
• Docfx version: Latest version

By following error message.

error NU1100: Unable to resolve 'docfx (>= 0.0.0)' for 'net7.0/any'. PackageSourceMapping is enabled,
the following source(s) were not considered: Package source.

It's assumed that PackageSourceMapping is customized on your environment,
and failed to resolve docfx package by custom package source (name: Package source).

What would be the result when running the following command?

dotnet nuget list source

On my windows environment. following message is displayed.

Registered Sources:
  1.  nuget.org [Enabled]
      https://api.nuget.org/v3/index.json
  2.  Microsoft Visual Studio Offline Packages [Enabled]
      C:\Program Files (x86)\Microsoft SDKs\NuGetPackages\

I thought, it need to find NuGet.config files that affects PackageSourceMapping.
and add PackageSourceMapping entry for docfx or register docfx.nupkg to custom package source.

Thank you! I was able to get version 2.67.5 installed, but when I run docfx commands, it's still using an older version.
PS C:\Program Files\dotnet> dotnet tool update -g docfx
Tool 'docfx' was reinstalled with the latest stable version (version '2.67.5').
PS C:\Program Files\dotnet> docfx --version
docfx 2.59.3.0

How do I get docfx commands to use version 2.67.5? Where is version 2.67.5 installed?

What's the result of following command?

where docfx
SET PATH

I thought docfx is installed by other package manager (For example, chocolatey or scoop).
And PATH priority is set higher than .NET Global Tool's path (%UserProfile%\.dotnet\tools)

Thank you! The path priority was the issue. I appreciate your help.
