So you've been able to install LW in the past? Which was the last version that installed properly? What's changed since then - new hardware, new/updated software etc?

Have you tried installing older versions of LW, to see whether the problem's version related? Try the older version in post #4.

Have you been able to install other p2p apps that aren't Java based (LW, Phex & FW all are)?

Try the version of BearShare mentioned here & see whether that installs: http://www.gnutellaforums.com/open-d...sabotaged.html

Did you try reverting back to an older Java version (in the 'fixes for LW' link, there's a link to an older Java)? When you switch Java versions, are you making sure to run only the one version of Java at a time?
