WinCab 3.1.4 doesn't create new database.

[JustMichael]

If you have "UpdateIndex = False" in your jukebox.ini file and no song database (like from a fresh install) then WinCab 3.1.4 does not ignore the False and create the song index.  WinCab just tries to compare the songs it finds to the index (which there isn't an index so it goes REALLY QUICKLY) and finds no matches and then gives the following message:

FATAL ERROR!
No songs found!
Check the SongPath setting in JUKEBOX.INI

A simple change to "UpdateIndex = True" will have it create the database.

It sounds as if the database was deleted but the path index file was not.  It checks for the existence of the path index, not the actual database.

and no song database (like from a fresh install)

Path index file?  So you are saying that new install already has this "path index file"?  The ONLY thing I find in the data subdirectory is "Remove.Me".  Even when that is removed, WinCab still doesn't create the database.

Try this:
Unzip a fresh copy of WinCab someplace.
Edit jukebox.ini and add a songpath AND change "UpdateIndex" to False.
Save jukebox.ini (also change it from read-only).
Run wincab.exe

Wincab will find all the songs and compare them to its non-existent database to see if they are in the database.  It will then error out after checking all the songs.  You can also get wincab to do this by renaming the "data" subdirectory to something else.
