Following your advice, I have reinstalled Java 2.2.5. Now all elementy are in the following order, namely:
MRJ Enabler in Ext. Folder
MRJ Libraries folder in Ext. Folder
MRJ Cache folder in Application Support Folder
All looks correctly, but the same result:
During time extraction of LimeWire Installer, the Trash is filled with the following files:
1- InstallAnywhere SEA.log
2- IA JavaInstaller (delete) 38252 - folder
3- IA MRJInstaller (delete) 671088 - folder
Also I have found in Preferences Folder one strange file named "MRJPluginAppletOutput" *which looks like a text file.
