I am running win2k sp1. I was getting an 1628 error or something like that after the instmsiw.exe and isscript.msi ran. I completely removed limewire and java, reinstalled java, downloaded and ran the instmsiw.exe and isscript.msi, then after reboot i turned off Adaptec, the programs for my mouse and keyboard, and anything else i could. Then i installed on a fat32 partition (i was origianlly trying to install on NTFS), and it worked fine. hope this can help someone.
