On the 5.1.0 CD a case exists where reinstalling HP7 ds391 will cause the
pop-up message "newer files exist" to appear.
The cause is the list of "latest" files in one of the ds390.da alias files
has older file dates than the actual files on the CD.
This won't be seen on the initial install, or on an install of 5.1.0 on top
of 5.0.0. It will be seen on a reinstall of 5.1.0 on top of 5.1.0.
If it does occur, the message can simply be ignored; if you choose to
reinstall the file, it will simply overwrite with an identical copy. If you
do not, the original (correct) copy will remain.
