As mentionned in the note #766191 and #891202, I did install Active Component framework (xACF_NW04s) and Adobe Acrobat reader 7.0.8 but still doesn't work.
I also uninstall xACF.exe first.
I have IE 6 and Win XP. Any suggestion?
Last thing that I don't know it is the SAP GUI. Since it is distributed by an installation server, how can I know if I have this component?
