When version 5 is running, on the Navigation Tree, click History Files.
On the tool bar on the main window, click Browse, and browse to the file you wish to view.
Once selected, it will appear as a file name under History files and it can be displayed and manipulated the same as if it was an online page under Recorder Home.

For external history viewer version, create a shortcut to c:\microscan\mscanv5.exe and add the command line /h, as shown below.

Microscan then starts in the history viewer mode, operates as above, but only has "History Files" in the navigation tree.
