Download the following file by right clicking and selecting "Save target as".
Save ALL files to your Downloads folder - DO NOT RUN anything yet.
Reboot your system.
BEFORE opening anything else, go to your Downloads folder and run the ActiveX Installer.
This did not work either.....altho it looked like it was going to at first. Still stopped at 50% with the same message about closing Internet Explorer.
Any other ideas?
If you REBOOTED, and I mean a HARD reboot... and ran the installer BEFORE opening ANYTHING, per the instructions... Internet Explorer CANNOT and WILL NOT be running for you to close.
