Hey guyz, when I unrar the Office2003SP2-KB887616-Client-ENU.exe (49.3 MBs): I got those files MAINsp2op.msp OWC11SP2op.msp OWC102003SP2op.msp plus other inf files, I'm wondering about the (op) suffix coz the slipstreaming process didn't work for me by msiexec /p C:\SP2\MAINSP2ffop.msp /a C:\Office2003\PRO11.msi SHORTFILENAMES=TRUE /qb msiexec /p C:\SP2\OWC11SP2ffop.msp /a C:\Office2003\OWC11.MSI SHORTFILENAMES=TRUE /qb Did i download something wrong? although I remove the op from the above 3 files to look like SP1 files I failed.....any idea what's going on?
