Hi, during my installation at T-13 when svcpack run this section : [SetupHotfixesToRun] HFSLIP.CMD DNF11.exe DNF20.exe DNF30.exe HFSLIP.CMD wmp11-windowsxp-x86-FR-FR.exe /quiet /norestart A dialog/error box appear saying switch for WMP11 are wrong and advise to type /? for more infomation, what i've donne and effectivly with my version of WMP11 (french localised) the switch seem to be : /Q Is it due to te localised version ? Or is there a trick I miss ? The funny thing is that a the end of the installation WMP11 is installed and seems to work.... Thanks Yoann
