Silent install with elevated credentials doesn't replace previous versions of Prism

After updating Prism to a newer version using the command-line with the '/quiet' key, there is a known issue in which the previous version of Prism will unexpectedly remain in the list of installed programs in the Windows Control Panel.

Prism itself is updated correctly, overwriting files in the program folder. However, a record in the list of installed programs for the older version of Prism is still present.

If you see numerous unexpected old versions of Prism in the list of installed programs in the Windows Control Panel, simply select the older versions you'd like to remove and click "Uninstall".

As the uninstall completes, the incorrect entry will be removed, while the newer Prism version will remain available.

We are working on developing a fix for this issue in future Prism versions
