Are you suggesting then to: Step 1: Install original MsnMsgs.msi (unextracted: 16mb) Step 2: Make sfx of apatched files write to %programfiles%msn OR Step 1: Compress ..... everything? actually i don't know this other step... as far as i know, after extracting MsnMsgs.msi (16mb) I get: PFiles MsnMsgs.msi (700kb) sirenacm.dll I once ran the 700kb file, .. it installs yes it does.. but it seem like when i run the wlm shortcut, it runs the msi installer again instead..... (linked to cd) ... which is so strange, so till now, i don't really have a clue if im doing the actual right thing.... i have many other addons, but this and office are the only ones i haven't figured out yet, probably due to this orca thing... please help :/ thanks i'd like to learn it myself if you don't mind giving me the instructions. lemme know what programs are necessary.. is it alright with you?
