Sorry, my question was not detailed enough. That is what I did. On my WinXP, I have installed WMP 11, then set all I was asked (confidentiality, file association, etc...). Then I closed my WMP and proceed the way you mentionned by selecting yes to all I was asked in the mpedp.exe cmd box. The msi file is created without errors and when I launch it, whatever the suffix is, it expands in a temporary folder and right after this launches the /help window. When I click OK, the install process is stopped and the temporary folder is deleted. The problem is that I don't see the meaning of this /help box appearing. I initially thought I had written the wrong suffix but I tried everything and it won't change. BTW, could you explain me what a URGE setup is? Thank you for your help
