LumenRT fails to start on Windows 7 (error with WS2_32.dll_unloaded)

In some cases, LumenRT fails to start on Windows 7, with this error in the Windows event viewer (eventvwr.exe):

Application name with errors: LumenRT.exe, version: 0.0.0.0, timestamp: 0x5cf51d8d
Name of the module with errors: WS2_32.dll_unloaded, version: 0.0.0.0, timestamp: 0x573365bb

This is a very rare issue, for which you can try this workaround:

- Open Windows registry editor (regedit.exe)
- Look for this key: HKLM\Software\Microsoft\SQMClient\Windows\CEIPEnable
- If the key is set to 1, change it to 0
- Restart LumenRT

Note: this registry key controls a Windows feature named "Customer Experience Improvement".
There is generally no harm in disabling this feature.
However, it is still unknown why it interferes with LumenRT.
