hey guyz I had 2 error messages along with failing to install the MUI, while when I installed it manually i got the same 2 errors but had success to change the interface however, this is my cmdlines may clarify what's wrong I did and how do i know which SP is my MUI files? coz I got XPSP2+RyanVMized+Nlited+Xpized [COMMANDS] "useraccounts.cmd" "muisetup.exe /i 0401 /d 0401 /l /f /r /s" "RunOnceEx.cmd" my needs are an Arabic interface from the first boot, TIA I found PCHDT_W3.CA_ in the original windows CD, and it's 2.5 MBs also HELPSVC.EX_ seems for the Help & Support Services (Crap!) anyway, definitly I removed the crap HELP by nlite but is it required for MUI Installation?! and even though I re-add these 2 files from my original windows CD, still got the same 2 erros first error second error
