After digging though the Log file, I think I have got the real error.
Error number 2679: Custom Action Do_WMISecurity.D20239D7_E87C_40C9_9837_E70B8D4882C2 did not close 1 MSIHANDLEs.
Here's the excerpt:

Like I said in my previous post, the erro occurs during the following step
"Installing WMI Registration"
Does anyone have any idea about Error 2679 ?
