It is not recommended to install over the net for dial up users. And probably the Java stage where it was calling on Java to downld may have mucked things up.
This is a tough one since you have no uninstaller. And no, with the present installer type you'd normally uninstall via the Start menu >Programs>LW>Uninstall or just go to the folder & find the uninstaller.
Let's try this. 1. Install Java 1st:
http://java.sun.com/j2se/1.5.0/download.jsp (take the JRE) & choose the offline one which is about 15 MB in size (
1st on list here)
2. Downld this LW version: See
Here about other version. SO you just unzip it & use it. When it installs, the initial stage will hopefully uninstall the previous attempt.
