We have an issue with our new Windows 7 machines (64 and 32 bit.) We are not getting prompted to install ActiveX at all with IE8 and IE9. When we go to a site where we know we should be prompted for install, we just get a blank page with a red X instead. No prompt and no install. This works fine in XP, but we are upgrading our equipment and XP is not an option anymore. It is not just one specific ActiveX.
Reset the browsers.
Opened up all of the ActiveX security in the browsers to see if it would prompt.
Tried to repair/find missing .dll files.
Roll back versions from IE9 to IE8.
Wiped a machine entirely and did fresh installs of everything.
Ensured all was completed on administrator profiles.
Tested on multiple machines in various scenarios.
