versions of Internet Explorer, it sounds like you might be opening the 32 bit version.
Right click on the icon you are using to start Internet Explorer and see what the path to the executable is. If it is something like C:\Program Files (x86)\Internet Explorer\iexplore.exe (note that (x86) in program Files) then you are using the 32 bit version. Locate the 64 bit version in C:\Program Files\Internet Explorer\iexplore.exe.
If you have Internet Explorer open and click on Help > About Internet Explorer. If it doesn't mention 64 bit, it's 32 bit.

I get a message that setup needs to close programs and I have a choice to Close programs for me and to ignore any open programs. I have tried both ways and always get this message in return: Internet Explorer did not finish installing. See the Internet Explorer Troubleshooter, which I have been to but does not help
On this site http://www.msn.com/?ocid=hmlogout, the IE 9 free download, I get a message that IE9 is now installed and to restart computer, After it is restarted I go to Internet Explorer, and do alternate H and it shows I still have IE 8.
I have run a disk check for errors, Went to Microsoft Fixit to try to fix IE. That did not work so I let Fixit reset IE 8. Then have gone back to try to install IE 9 and get the same messages as above. Not sure what to do now
