# Reinstall iisnode - Step by Step
|
||
|
|
|
||
|
|
## Current Issue
|
||
|
|
iisnode error 0x00000002 - can't execute Node.js
|
||
|
|
|
||
|
|
## Solution: Reinstall iisnode
|
||
|
|
|
||
|
|
### Step 1: Uninstall Current iisnode
|
||
|
|
1. Control Panel → Programs → Uninstall
|
||
|
|
2. Find "iisnode" → Uninstall
|
||
|
|
3. Or manually remove from: `C:\Program Files\iisnode`
|
||
|
|
|
||
|
|
### Step 2: Download Fresh iisnode
|
||
|
|
- Go to: https://github.com/Azure/iisnode/releases
|
||
|
|
- Download: **iisnode-full-v0.2.26-x64.msi** (or latest x64 version)
|
||
|
|
- Make sure it's **x64** (not x86)
|
||
|
|
|
||
|
|
### Step 3: Install
|
||
|
|
1. Run the .msi file as Administrator
|
||
|
|
2. Follow installation wizard
|
||
|
|
3. Make sure "Register iisnode with IIS" is checked
|
||
|
|
|
||
|
|
### Step 4: Restart
|
||
|
|
- Restart IIS: `iisreset`
|
||
|
|
- Or restart computer
|
||
|
|
|
||
|
|
### Step 5: Verify Installation
|
||
|
|
1. Check: `C:\Program Files\iisnode\iisnode.dll` exists
|
||
|
|
2. IIS Manager → Server → Modules → Should see "iisnode"
|
||
|
|
3. Test with hello.cjs
|
||
|
|
|
||
|
|
### Step 6: If Still Error
|
||
|
|
Check Node.js version compatibility:
|
||
|
|
- iisnode v0.2.26 works with Node.js 12-18
|
||
|
|
- If Node.js 19+, might need newer iisnode version
|
||
|
|
|
||
|
|
## Alternative: Try Without nodeProcessCommandLine
|
||
|
|
Sometimes letting iisnode find Node.js automatically works better.
|
||
|
|
|
||
|
|
Remove from web.config:
|
||
|
|
```xml
|
||
|
|
nodeProcessCommandLine="C:\Program Files\nodejs\node.exe"
|
||
|
|
```
|
||
|
|
|
||
|
|
Let iisnode use PATH to find Node.js.
