We are seeing large numbers of users who can no longer use Add-Ons in Internet Explorer 7.0... which means they cannot download and install Microsoft software that requires ActiveX OK. The problems we are seeing most often appear in Windows XP Professional The fixes posted by Microsoft too often do not work. Nearly all of these problems seem to have appeared on computers using Firefox or other alternate Internet software. Is anyone else seeing this problem. Does anybody have a fix that allows the user to return to the normal version of Internet Explorer 7.0 that allows Add-Ons and the selection of ActiveX on Microsoft Downloads?
