Actually, it's not only "certified 100% ugly" software it is useful for.

It is also useful for big software (1 or 2 GB, YMMV) packages where:

1. There is no uninstall / registry check,
2. You're not sure what file (for file check) is copied as the *last* 
one. This also applies to the above uninstall / registry check if you're 
not sure it's installed at the very end.


Consider this:

1. User powers on the workstation, WPKG installs a 2 GB software package.

2. After 1 GB is copied, a uninstall / registry entry is added by the 
installer, or a file (main_file.exe) you have in a file check is copied. 
Still, there is 1 GB left.

3. User powers off the workstation.

4. On the next bootup, WPKG checks conditions, assumes everything is 
installed cleanly (checks match, don't they), software doesn't work, 
user complains and helpdesk calls...
