That's exactly the solution to the problem. Mac OS X is a little too fussy about what it regards as application packages and what it thinks are folders. If there's something already there with the same name, Stuffit Expander automatically appends a "1" to the end of the name. This seems to go *after* the invisible ".app", breaking Mac OS X's automatic recognition of that item as an application... so it makes it into a folder.

There's probably a tool out there to convert folders into packages, and you may be able to do thsi by hand anyway - haven't tried yet, personally - but the simplest thing to do is rename or move the original "install" item and unstuff the Limewire thing again. The new item will be named correctly, and work properly.

NOTE to the LimeWire developers: could you please name the actuall installer app something more explicit than just "install"? That could refer to just about anything, and it could be 'sorted' out of site in the containing folder very easily. Something like "Limewire Installer" would be good, and sticking the version number in there (for example "LimeWire 2.0 Installer") would be even better - that would avoid much of the 'app is folder' problems too! :-)
