# OLE Dispatch Exception Code 0 SWbemObjectSet: Invalid Class

You can receive error **0x80041010** from multiple applications that call WMI. For my example it was received in Computerlink while checking for the port server process.

This can be triggered by running the **systeminfo** command in a command prompt or applying patches in SCCM.

No matter where you got the error the underlying issue is probably with WMI. Here is how to check!

### Confirm WMI is Broken:

Launch the WMI MMC snapin by clicking **Start -> Run** then enter **wmimgmt.msc**

Right click **WMI Control (Local)** and click **Properties**

If WMI is working properly then it will show the system information. If you see **Invalid class** then your WMI is not working correctly.

**Good**

### The most likely cause is MOF Registration Errors

To resolve MOF Registration errors the following command needs to be ran from an **elevated** command prompt. It will reregister all .MOF files with WMI.

```bash
CD C:\Windows\System32\WBEM dir /b *.mof *.mfl | findstr /v /i uninstall > moflist.txt & for /F %s in (moflist.txt) do mofcomp %s
```

Here is what the command looks like while it runs:

Once finished check wmimgmt.msc to see if it is populating the Properties correctly.
