Choosing 'Export' and attempting to open the resulting search file results in another application opening instead of Search Exporter.
The 'amexp' file extension is associated with another application.
Remove the existing file association within Windows for 'amexp' and re-associate with the Search Exporter executable.
The default path for the Search Exporter executable on 64-bit Windows is the following:
"C:\Program Files (x86)\Quest Software\ArchiveManager\Archive Manager Search Exporter\SearchExport.exe"
