```

### What Happened Automatically
1. **Conflict Detection:** Found old wrapper in G:\Program Files\nodejs\
2. **Automatic Cleanup:** Removed old installation without user prompt
3. **PATH Management:** Added %USERPROFILE%\bin to user PATH
4. **Zero User Interaction:** No prompts, no errors, exit code 0

## Verification Tests

### 1. Direct Execution (Before Restart)
```powershell
& "$env:USERPROFILE\bin\openclaw.cmd" --version
```
**Result:** ✅ OpenClaw 2026.3.13 (61d171a)

### 2. Dashboard Launch (Before Restart)
```powershell
& "$env:USERPROFILE\bin\openclaw.cmd" dashboard --no-open
```
**Result:** ✅ Dashboard URL: http://127.0.0.1:18789/

### 3. Installation Integrity
```powershell
Test-Path "$env:LOCALAPPDATA\openclaw-installer\openclaw\node_modules\openclaw\openclaw.mjs"
Test-Path "$env:USERPROFILE\bin\openclaw.cmd"
```
**Result:** ✅ True, True

### 4. Old Wrapper Removed
```powershell
Test-Path "G:\Program Files\nodejs\openclaw.cmd"
```
**Result:** ✅ False (successfully removed)

## Critical Bugs Fixed

### Bug #1: Missing cwd Parameter
```python
# BEFORE (broken):
subprocess.run(cmd, capture_output=True, text=True, env=env)

# AFTER (fixed):
subprocess.run(cmd, cwd=str(install_dir), capture_output=True, text=True, env=env)
```
**Impact:** Packages installed to wrong directory, wrapper couldn't find openclaw

### Bug #2: Old Installation Conflicts
```python
def _clean_old_installations(self) -> None:
    # Automatically removes old wrappers from common locations
    locations = [
        "C:\\Program Files\\nodejs",
        "G:\\Program Files\\nodejs",  # User's non-standard location
        # ... other locations
    ]
```
**Impact:** Prevents PATH conflicts and MODULE_NOT_FOUND errors

### Bug #3: Path Resolution
```python
def _get_openclaw_path(self) -> Optional[Path]:
    # Direct file path check, no npm commands needed
    return install_base / "openclaw" / "node_modules" / "openclaw" / "openclaw.mjs"
```
**Impact:** Works even when system npm is completely broken

## Architecture Overview

```
Installation Layout (Isolated from System Node.js):
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

%LOCALAPPDATA%\openclaw-installer\
├── node\
│   ├── node.exe (v22.16.0)
│   ├── npm.cmd
│   └── node_modules\
│       ├── npm

│           └── ...
└── npm-cache\
    └── _logs\

%USERPROFILE%\bin\
└── openclaw.cmd (wrapper with NODE_PATH set)

System Node.js (untouched):

## Cross-Platform Compatibility

| Platform | Node.js Location | Wrapper Location | Installation Base |
|----------|------------------|------------------|-------------------|
| **Windows** | %LOCALAPPDATA%\...\node\ | %USERPROFILE%\bin\openclaw.cmd | %LOCALAPPDATA%\openclaw-installer\ |
| **Linux** | ~/.local/.../node/bin/ | ~/.local/bin/openclaw | ~/.local/openclaw-installer/ |
| **macOS** | ~/.local/.../node/bin/ | ~/.local/bin/openclaw | ~/.local/openclaw-installer/ |

## Conclusion
