64 bit MS Security Essential.

  1. Mar 25, 2014 #1
    I just got my Win 7 64 bits computer. I went to Microsoft site to download the Security Essential. But when I tried to install the program, it said it's for a 32 bit computer and I need to get the 64 bit one. I went on MS site and looked all over, typed in "64 bit Security Essential". But I kept getting back the same 32 bit program. What did I missed? Anyone can give me a link to the right program?

    My computer is an HP with 4th generation I-5 processor.

    When I tried the first link, the download biutton gave me a choice of files with amd64 and x86 in the names. I guess the amd64 is 64 bit and x86 is 32 bit.

    What web browser are you using? Some Microsoft web pages query what operating system and version (32/64 bit) you are running and alter the content of the page to match, but some non-Microsoft browsers give the OS information information incorrectly. (Actually, even some MS browsers give the information in a confusing but correct way, but you would hope MS knows how to deal with that!)

    If you were were using Firefox, Chrome, etc, try again using Internet Explorer.

    Thanks for the reply. Isn't the AMD64 for AMD chipset?

    Yes, I use Firefox. I'll try using Internet Explorer.

    intel64 and amd64 are the same thing:
    Prior to launch, "x86-64" and "x86_64" were used to refer to the instruction set. Upon release, AMD named it AMD64.[3] Intel initially used the names IA-32e and EM64T before finally settling on Intel 64 for their implementation. Some in the industry, including Apple,[4][5][6] use x86-64 and x86_64, while others, notably Sun Microsystems[7] (now Oracle Corporation) and Microsoft,[8] use x64 while the BSD family of OSs and several Linux distributions[9][10] use AMD64.

    Thanks, the AMD64 installed successfully. I did not know as I read AMD and think it's for AMD.
