MCP Server - cannot run NPX

I cannot run MCP Servers in AI Assistant. 
For example, this server:

{
  "mcpServers": {
    "jetbrains": {
      "command": "npx",
      "args": [
        "-y",
        "@jetbrains/mcp-proxy"
      ]
    }
  }
}

I receive an error:

Cannot run program "C:\Program Files\nodejs\npx": CreateProcess error=193, %1 is not a valid Win32 application
