# Microsoft Office Patch Download - Extraction Issue in Patch Store

During Office patch downloads, ManageEngine uses the **Office Deployment Tool (ODT)** to fetch update files from Microsoft CDN.

If the **setup.exe** inside the patch package fails to extract properly into the Patch Store, the download process fails.

## Symptoms

Office patches stuck in **Download Failed** status.

**Remarks** shows entries like:

- Unable to execute command
- Command execution failure
- setup.exe not found / extraction failed

`%temp%\OfficeSetup[<timestamp>.log` may show:

- Failed to extract setup.exe
- Access denied or file corrupted

## Possible Cause

1. Insufficient privileges for the service account running ManageEngine.
   - Cannot write to the Patch Store folder.
2. Antivirus or endpoint protection blocking .exe extraction.
3. Corrupt download of the Office Deployment Tool (ODT).
4. Read/Write permission issue in the Patch Store directory.
5. Disk space issues preventing extraction.

## Resolution

### Step 1: Verify Patch Store Permissions

- Navigate to the Patch Store: `<manageengine>\PatchRepository\`
- Ensure the service account (the one running ManageEngine services) has Full Control (Read/Write/Execute) on the folder.

### Step 2: Manually Test Extraction of ODT

- Download the latest [Office Deployment Tool](https://www.microsoft.com/en-us/download/details.aspx?id=49117) from Microsoft.
- Copy it into a test folder (eg:. C:\o365)
- Use 7-Zip or Windows’ built-in extraction tool to unpack the .exe file, and then confirm that setup.exe has been successfully extracted.
- If manual extraction fails, re-download the ODT (corrupted file).

### Step 3: Check Antivirus / Security Policies

- Temporarily disable antivirus or add exclusions for:
  - `<manageengine>\PatchRepository\`
  - `%temp%\OfficeSetup*.log`
- Ensure .exe extraction is not blocked.

### Step 4: Disk Space Validation

- Ensure sufficient free space in the Patch Store drive.
- Office updates require several GB free for extraction + caching.

## Manual Troubleshooting with Commands

### Test Extraction with ODT

```
setup.exe /extract:C:\o365\ /quiet
```

- Should create setup.exe + supporting files in the target folder.

## Log Locations

**Office Setup Logs (Temp folder)**

- `%temp%\OfficeSetup[(timestamp).log`

**System Temp (if running as service)**

- `C:\Windows\Temp\OfficeSetup[<timestamp>.log`

## Next Steps

If extraction still fails after these fixes:

- Collect Server Logs and %temp%\OfficeSetup.log.
- Verify folder/file permissions.
- Escalate to ManageEngine support with logs.
