There are several other insights that indicate you are not running .NET v4.8 Framework. These are listed below:

- The Viewer closes on its own after you open it

- The Viewer Time Span date and time does not advance. Select the Inventory view and set the Time Span to *All.* The *To *date shows the last time data was stored

These behaviors indicate SiteAudit was installed but it cannot connect to the database. Therefore you need to install .NET v4.8 Framework to complete the installation.
