What's Wrong?

Downloading the installer shows an error message

Install fails and Claude keyword does not work

Manual workaround for others who run into this :

 Method 1: Using GUI (Recommended for most users)

  1. Open Environment Variables:
    - Press Win + R to open Run dialog
    - Type sysdm.cpl and press Enter
    - Click the Advanced tab
    - Click Environment Variables button
  2. Edit User PATH:
    - In the User variables section (top half), find and select Path
    - Click Edit
  3. Add the directory:
    - Click New
    - Add: C:\Users<username>.local\bin
    - Click OK on all windows
  4. Apply changes:
    - Close and reopen any terminal windows (PowerShell, CMD, Git Bash, etc.)
    - The new PATH will be available

  Method 2: Using PowerShell (Quick)

  Run PowerShell as Administrator and execute:

  [Environment]::SetEnvironmentVariable(
      "Path",
      [Environment]::GetEnvironmentVariable("Path", "User") + ";C:\Users<username>.local\bin",
      "User"
  )

What Should Happen?

Claude installer should properly prepare the PATH variable and install properly

Steps to Reproduce

install with PATH already used. In my case it was previously used for several other things including a python install.

Had to manually add the C:\Users\mattloc24.local\bin and the problem was resolved
