After changing order of integration this is the same: impossible to open "Manage add-ons" window. - I've tried in VMWare Workstation to uninstall everything: hotfix, Framework, WMP11 Java etc ..... Ther's NOTHING installed on my machine, and I can't open this #%@-/§:: window ! - After Reseting configuration of IE7: idem ! I don't know what to do now to open "Manage add-ons"! Is ther any body in the world with the same problem ??? -------------------------------------------------- MESSAGE REEDITED A FEW MINUTES LATER: system32/extmgr.dll is not properly registered ! This file is included in IE7 pack, but is NOT registered when IE7 is installed. If I try ro register extmgr.dll, it does not work, but if I try to register the same file in the uncompressed directory of IE7 originel Package, it works fine, my "Manage Add-ons" appears ! So I understand extmgr.dll NEEDS another file in the same directory of itself to be properly registered and to work.... to be continued ... see you soon
