ALRIGHT!!! I've read all the postings/responses I could find on 'Command Line Parameters' error and NOBODY seems to know the answer!! Come on now! Doesn't anybody from LIMEWIRE tech support ever read this forum??? I KNOW there is a simple answer because I had this problem a year ago and I found the answer and fixed it. I guess that proves you need to WRITE DOWN stuff, huh! SOMEONE, PLEASE, PLEASE HELP ME!!! My error is the same as 12 others! :
Command Line parameters
/L language ID
/S Hide initialization dialog for silent mode use: /s
/v/qn
/v parameters to MsiExec.exe
/UA<url to InstMsiA.exe>
/UW<url to InstMsiW.exe>
/UM<url to msi package>

I'm running WinXP and have downloaded the lastest 2.5 ver of Limewire.
