Win7 - MS apps as 32bit and 64bit

    I am new to 64Bit Windows and I just installed a Win7 64Bit 90 days Test
    version to evaluate.
    I found that most of the native MS apps like Mediaplayer a.s.o. are
    installed twice, in seperate folders for 64Bit and for 32Bit apps.

    Does somebody have a link where I can do some reading to get to know why
    everything is installed twice and why it needs seperate program
    folders for 32Bit and 64Bit apps?

    I'm not sure there's much to understand. 64 bit apps go in Program Files
    and 32 bit apps in Program Files (x86). MSFT provides both 32 bit and 64
    bit versions of some apps that are included with Windows and they each get
    installed in their respective folders.

    That was correct for Vista x64.
    Win 7 has embedded codecs for most of the popular formats, both in x86 and
    x64 versions.
    Moreover Directshow type codecs (the ones used by ffdshow) run at a lower
    priority. The new buzzword is Windows Media Foundation. Those are the
    preferred codecs used by WMP and WMC.

    OK, thank you guys.
    This means that I just leave these apps as installed by the setup to not
    mess up with other apps that might need the 32Bit version ... or the
    64Bit version.
    Its kinda like a 'Deja-vu', yeeaaars ago when we moved from 16Bit to
    32Bit. ;-)

  5. Very much like the move to 32-bit. Only more so, since MS dropped support
    for ANY 16 bit applications, and for DOS applications. They simply won't
    run. (However, you can use the downloadable Windows VirtualPC plus XPMode to
    run them virtualized.)

    Internet Explorer is a clear example of why it exists in two flavours:
    32-bit and 64-bit.
    All add-ins/plugins are fully functional with IE32, as usual.
    Not all add-ins/plugins are functional (Flash isn't) with IE64.
    If you can live without Flash (some enjoy it!) then go for IE64.

  7. Charlie,

    I have a 16 bit application from 1995 that will not run under Windows XP
    Mode. Well, it does, but not on the Windows 7 desktop.

    Any ideas?

    Install freeware virtual machine Virtualbox (
    Later on install any 32-bit OS you may have stashed in your shelves and try
    your 16-bit "oldie".
    Brute force, but it will surely work!

  9. The whole idea of Windows XP Mode is that the 16 bit program should be
    virtualized on the Windows 7 desktop. It isn't. The program works just fine
    in M/S Windows XP Mode under Windows Virtual PC.

  10. First, is the RAIL technology working for other applications? That's the
    first requirement. Second, you'll need to install your 16 bit application
    into XP and make sure that it is added to the All Users start menu.

    Unfortunately, right now I don't have any machine that can run XP Mode,
    since all my machines that support hardware virtualization are busy running
    Windows Server 2008 R2. I had a spare machine for this, but it blew a
    motherboard, and I haven't been able to replace it yet. Since it's an OLD
    D920 processor, I'm not terribly inclined to spend much on it. Frankly, I'd
    rather build a new machine from scratch.

    Question, is the program written in 16 bit mode or just the installer?

    If it's the installer only you may be able to copy the installed
    program from an earlier machine into Win7, that worked for me because
    the program didn't make any registry entries.

    If it's the whole program your only choice might be to find something
    similar that will run in Win7. I'm guessing the company that created
    the application is not updating it or, like my app mentioned above, the
    new program is so bloated it's (to me) completely unusable!
