Thansk a lot XtremeMaC Now I can try with this version (DX9NTOPK.EXE). 2003/12/15 : Here are the results from the Windows Update: Critical 819696 "DirectX9" missing! Non-critical "DirectX 9.0b Final" missing! There area also some other strange points: DotNetFX missing. Perhaps bacause I didn't include the language pack!? But how to be sure the language pack will be installed AFTER the DotNetFX core? Journal Viewer: error on install. Finally, Non-critical 820223 "Update for OE SP1" missing. This one should be added (in HFTYPE2?) for some non-English languages (see http://support.microsoft.com/?kbid=820223) Non-critical 826942 (WPA) missing. New patch, it should be added. 2003/12/15 later : During the installation process, the error "This update requires OE 6.0 SP1" is displayed (followed by an endless installation loop!) I am suspecting the 820223, but not very sure In any case slipstreaming WinXP SP1 before anything else, makes sure that my WinXP has OE SP1; so, I don't understand anymore
