Have Windows 7 Ultimate 64-bit (No SP-1 yet). When installed, have both IE 8 32-bit & IE-64bit. I want to upgrade to IE9; when I loaded IE9 32-bit and selected up grade it asked me to save IE-64bit. I have also found IE9 32-bit but this time do I install both or not, can't find infomation about this subject?

Download the x64 bit version. It is the correct setup for your machine and should upgrade you to IE9. It will install both the 32-bit and 64-bit versions on your computer.
