Reason being - This will show a discrepancy between Installer version (preferred evidence) vs. actual version being used in a cached folder (file evidence). And many of these cached folders will not be scanned as they may be 'noisy' & bloat systems.

Example for Webex - the cached user App Data file has the newest Webex installation and executable files, whereas the Program Files & Registry entry stay at the older version.

This is also due to profiling - for situations where multiple users share a device, they might have different versions in their respective folders.

Thanks!!
