They all have it but individually. First open an IE6 browser, click Help, then About...check the 2nd line, below the Version# (the Cipher strength should be 128 bit. Then close the browser, go to Start, Settings, Control Panel, Add/Remove Programs.Find Microsoft IE6 Browser & Tools, highlight it & click on the Remove Button. Choose Repair & reboot when requested. (If the Cypher was less than 128 bit, Choose Add to the browser and find the necessary items you wish to add).(Those listed in BOLDprint should be installed already). Then reboot, or you can just choose to go back to your previous installation of IE5.0 or 5.5 and start the download process again for IE6.
Also you can check the security settings as was said by another above...open the browser, click Tools, Internet Options, then the Security Tab. Set all 4 zones individually to the "Default" level.
